The word “move” is used in the context of an offseason to denote any number of varying transaction types. A trade is a move. A free-agent signing is a move. A player being designated for assignment is a move, or claimed off waivers, or sold to Japan. Players coming and going from rosters are the moves of the winter, and they’re the means by which the public tends to evaluate a team’s offseason.
The calculus for the outlook of the upcoming season is constantly changing throughout the offseason as these myriad moves transpire. When a team signs a star free-agent pitcher, we know that that team is several wins better than they were the day before. When a rebuilding club trades away its slugger in the final year of his contract for prospects, we understand that they’ve dropped a couple wins for the upcoming season.
But there’s another sort of move that happens during the offseason that’s more subtle, and it, too, changes the calculus of the upcoming season, though it often seems to be overlooked. We spend so much time and effort analyzing who “won or lost” the offseason that it’s easy to forget how much change should be expected from a team’s returning players. The Rangers didn’t go out and sign Yu Darvish this offseason, but he is expected to be a valuable addition to this year’s roster, an extra four or so wins added without any kind of traditional offseason move. Without doing anything, the Rangers rotation looks significantly better than it did at the end of last year.
Six years ago, Dave Cameron wrote a short post on this site titled 2009 Is Not a Constant. I recommend you read it, and sub in “2015” for “2009” when applicable, but here’s a relevant passage anyway:
We all know about career years and how you have to expect regression after a player does something way outside the ordinary, but regression doesn’t just serve to bring players back to earth after a big year.
Regression “fixes” a lot of problem spots from the prior year, even if the team doesn’t make a serious effort to change out players. The Royals got a .253 wOBA out of their shortstops a year ago. I don’t care how bad you think Yuniesky Betancourt is, you have to expect that number to be higher this year. They didn’t do anything to improve their shortstop position this winter, but the level of production they got from the position in 2009 is not their expected level of production for 2010.
You cannot just look at a team’s prior year won loss record – or even their pythagorean record – make some adjustments for the off-season transactions, and presume that’s a good enough estimator of true talent for the 2010 team.
By now, you’ve got an opinion of most every team’s offseason. You know the Tigers have signed two players to nine-figure contracts, and you’ve adjusted your perception of next year’s Tigers accordingly. You know the Braves have traded away anyone with a major-league uniform left over from 2015, and you’ve adjusted your perception of next year’s Braves accordingly. What you’ve probably spent less time doing is factoring in how much is expected to change at the positions where teams stood pat.
So what I’ve done is taken projected WAR, by Steamer, for every player who’s expected to receive regular playing time this year. For position players, I called it 300 plate appearances, and for pitchers, 100 innings. For all those same players, I calculated the difference between their projected 2016 WAR, and last year’s actual WAR, and I only looked at players who remained on the same team. The methodology might not be perfect here — it’s a summed total, and some teams have eight regulars returning while others have 13 — but this post isn’t about the exact figures, or determining a precise order. This is just about finding teams who can likely expect an overall bounceback from their core group of returning players, or perhaps an overall regression. It’s about reminding ourselves not to forget the hidden part of the offseason’s calculus.
This is something worth thinking about for every team, but we’ll go over a few of the extreme examples below. The chart looks like this:
Largest expected gains from returning players
- Notables: Anthony Rendon (+2.9 WAR improvement), Stephen Strasburg (+2.0), Jayson Werth (+1.5), Wilson Ramos (+1.3), Tanner Roark (+1.1)
Despite a projected three-win regression from Bryce Harper, because even Bryce Harper shouldn’t be expected to repeat a 10-win season, the Nationals top the list. Which is fitting, because the Nationals were last season’s biggest disappointment, and yet the Nationals are again projected as the best team in the NL East, by a five-game margin. This is the big reason why.
Rendon shouldn’t be expected to miss half the season due to injuries, and assuming full health, he should also be better when he plays. Before the Nationals even made a move this offseason, they could factor in an extra ~3 WAR, just due to a clean slate from Rendon, who looked like an emerging superstar at 25 just a year ago. Strasburg pitched like Clayton Kershaw in the second half, and shouldn’t be expected to have an ERA over five through May again. Extra two wins there. A healthier season from Werth, a better BABIP and more normalized strikeout rate from Ramos and fewer expected home runs from Roark could mix in up to four more wins from the Nats returning regulars.
Boston Red Sox
- Notables: Hanley Ramirez (+3.9), Pablo Sandoval (+3.7), Rick Porcello (+1.9), Dustin Pedroia (+0.8), Rusney Castillo (+0.4)
The Red Sox are basically the American League’s version of the Nationals, what with their 92-win team projection that might appear bullish on the surface relative to their colossal 2015 disappointment. All of which is thanks to the players added during last year’s offseason.
Our opinions of Ramirez and Sandoval should absolutely have changed from where they were when the Red Sox acquired them a year ago. But I don’t think anybody actually believes Ramirez and Sandoval are two of the three worst players in baseball, as they were last season. If you think Ramirez and Sandoval turn in two-win seasons — essentially assuming they’re just league-average starters — you get a nearly eight-win upgrade from last season. A bounceback from Porcello — who underperformed his peripherals at a level that’s jarring, even for him — could add another couple wins.
The Red Sox made headlines by adding David Price and Craig Kimbrel this offseason without having to move any of their major league talent, but the bigger part of their projected improvement is due to the expected upgrades from within.
Largest expected dropoffs from returning players
Toronto Blue Jays
- Notables: Josh Donaldson (-2.8 WAR dropoff), Marco Estrada (-2.1), Edwin Encarnacion (-1.9), Kevin Pillar (-1.8), Ryan Goins (-1.3)
It’s not that Donaldson isn’t expected to continue being a star player. He’s still seen as a top-three position player in the game. It’s just that, like Harper, you can’t expect another MVP season, in January. You can’t expect +9 WAR. It’s more reasonable to expect something closer to +6 WAR, which is still amazing. Then, you’ve got Estrada, who can be expected to regress somewhat from a career year, though I do find Steamer’s projection of him to be overly pessimistic, personally. Encarnacion is 33, and power declines eventually. Steamer doesn’t buy Goins’ sudden spike in walk rate, or Pillar as a true-talent +15 center fielder. Again, that’s not to say Pillar isn’t projected as a plus defender in center — he is — we just can’t reasonably expect that kind of extreme defensive value after just one season as a regular.
San Francisco Giants
- Notables: Brandon Crawford (-2.5), Matt Duffy (-2.0), Gregor Blanco (-1.6), Brandon Belt (-1.6), Joe Panik (-1.5)
Steamer still thinks the Giants have a great infield, just maybe not the best infield in baseball again. Even if you think this looks a bit overly pessimistic, it’s easy to at least see where it’s coming from. Duffy came out of nowhere — an 18th-round draft pick who skipped Triple-A and didn’t do anything in his brief 2014 debut — and turned in a star performance last year. That Duffy is even projected as an above-average starter (+3 WAR) is remarkable, given where he was a year ago, but he isn’t seen as a star just yet. Panik was seen as a low-ceiling player who had never hit in the minors, and turned in a star performance last year. That he’s even projected as an above-average starter (+3 WAR) is remarkable, given where he was a year ago, but he isn’t seen as a star just yet.
As for Crawford, his projection seems particularly bearish. While last year’s power spike was unprecedented and likely unsustainable, he’s significantly outhit his projected wRC+ each of the last two seasons, and the defensive metrics never matched the eye test until this season, which are perhaps unfairly muting his defensive projection. Like Duffy and Panik, Crawford probably isn’t the star-level player he was last season, so you probably wouldn’t be wrong to confidently take the over on 2.2 WAR, but some regression should be expected.

It’s important not to get too hung up on the particulars of the figures. That’s not the point. The point is that what Dave wrote six years ago is just as true now as it was then. It’s not as simple as starting from a team’s 2015 record, factoring in the major offseason moves and calling it a day. You can’t look at Boston’s 78-win record from last year, and scoff at the notion that Price and Kimbrel will add 14 wins to that. They won’t. But there are reasons to believe the Red Sox will improve substantially in other areas, in areas where they didn’t need to make a move. The expectation shouldn’t be that the entire Nationals roster gets hurt or underperforms in May again. Josh Donaldson won’t be an MVP every season, and Matt Duffy won’t always be an All-Star. Most every team has examples of this. Not to say these things can’t happen again, but the surprises of last year were surprises for a reason. Remember the hidden moves of the offseason.
Note: While Brandon Crawford’s figures were reflected in the original calculation and chart, I accidentally passed him over in the write-up. The post has been edited to correct this.
