NFBC FAAB Breakdown & Week 17 Estimates

Finally. I have combed through all the NFBC Main Event FAAB bids, linked them to past CBS ownership rates, and I’m able to provide some interesting facts on the FAAB bidding process. Besides the overall FAAB breakdown, I have this week’s estimated FAAB bids.

I’d like to again thank NFBC’s Greg Ambrosius for providing the information on some missing weeks. There is no way this project could have moved forward without his help.

1. Overall Spending Rate

With the complete dataset, the ideal versus actual spending rates can be calculated.

Actionable Adjustments Inspired by First-Half Busts

Yesterday, I examined hitters who owners missed on preseason and what could be done to prevent such mistakes in the future. Today, the underachievers go under the microscope. In my previous article, I used Paul Sporer’s “All First Half” articles for reference. With no underachieving articles out yet, I will look for players with differences in ADP and current rank using our auction calculator.

Extended Injury Stays

Daniel Murphy

I lamented last offseason about missing out on J.D. Martinez’s great 2017 season. I didn’t want to miss out again and was willing to take a chance on Daniel Murphy’s discount.

When I created his projection, I account for six weeks off but it was on the short side. Additionally, once he returned, he wasn’t productive for a few weeks but has a .859 OPS in July.

Actionable Adjustments Inspired by First-Half Breakouts

We are all learning, modifying, or destroying ideas all the time. Rapid destruction of your ideas when the time is right is one of the most valuable qualities you can acquire. -Charlie Munger

It’s time to see if I need to adjust my fantasy baseball beliefs by analyzing the first half busts and breakout lists. While it’s great to acknowledge these players, owners need to sit down and figure out why everyone missed on them. By hitting on one or two of these breakouts, a team could be competing for the top spot. Here are the groups and how to identify the breakout next preseason.

For the player situations I analyzed, I’m used Paul Sporer’s First Half All Value Stars and Fantasy Team for inspiration. I looked for actionable traits or tells which can be used next season.

Unknown Playing Time

Jesus Aguilar

Everyone understood coming into this season that the Brewers playing time situation was going to be a mess, so not owning Aguilar is understandable. He was to be in a platoon with Domingo Santana with middling projections. The deal with Aguilar, he really didn’t have a horrible platton split. It was .372 wOBA vs .338 wOBA in 2017. It’s .444 vs .405 this season.

Top-75 Stats-Based Hitting Prospects

It’s time for the bi-weekly look at under-the-radar hitting prospects. There seemed to be some confusion on the point of the rankings which is to find under promote good prospects. Today, I will try to clear up the and dive into a few hitters not represented on top-100 prospect lists.

The last time I ran this report, there was some questions on why some hitters were missing. After investing, I found out it’s was a database issue which missed some newly signed players, changed the position labeling, and mislabeled when players lost their rookie eligibility. I’ve made sure everyone is included but added a few adjustments.

pERA Rankings With Starting Pitcher Sleepers

I’ve decided to update my 2018 pERA rankings since I’ve been diving for some starter sleepers. Usually, this procedure helps to find underperformers with inflated ERAs. This time, it was mainly under the radar pitchers.

If anyone is unfamiliar with pERA, it combines the swinging strike rate and batted ball data from each pitch along with the walk rate into an overall ERA estimator (full explanation). Besides the few pitchers listed below, here is a link to the full 2018 values.

The top starters are as expected:

Rank. Name: pERA
1. Max Scherzer: 2.34
2. Chris Sale: 2.44
3. Jacob deGrom: 2.52
4. Noah Syndergaard: 2.57
5. Ross Stripling (w/ RP stats): 2.65
6. Trevor Bauer: 2.75
7. Gerrit Cole: 2.83
8. Justin Verlander: 2.88
9. Patrick Corbin: 2.91
10. Dereck Rodriguez: 2.92

Two Intriguing Starters: Eovaldi & Suarez

During last night’s chat, I got the usual “Rank these five pitchers….” questions. Similar names kept popping up and I felt I was using dated information. I decided to dive into a couple pitchers to see if my previous valuations should be adjusted.

Nathan Eovaldi

The 28-year-old righty has always been a disappointment with a mid-90s fastball and a sub-7 K/9 strikeout rate. After missing the 2017 season for Tommy John surgery, the Rays starter is putting up his best season ever with a 3.35 ERA with matching ERA estimators.

The reasons for the turnaround can be inferred from this simple graph.

Week 16 FAAB Estimates

After my first attempt into the estimating FAAB bids, I’ve been working away matching up ownership jumps with the actual bids. I’m close to being done as I work backward from the most recent weeks to the season’s beginning. By using these most recent values I found some interesting conclusions along with FAAB estimates for this week.

First, thanks again to everyone who has suggested any improvements. I’m trying to implement as many as possible. Second, if you are reading this more than a week from the publish date, look for newer articles. I’m just at the initial stages of creating the FAAB estimate equations.

As for information I’ve found out.

1. Owners spend a ton of FAAB chasing Saves. Of the top-10 players with the most money spent on them from week 13 to week 15, six were potential closers with 27 teams spending $1550 on A.J. Minter in week 14.
One issue possibly driving this high value is that for a team to win the overall NFBC prize, they must beat all the other 509 owners. They can’t dump a category. Owners who are behind with Saves are still grinding away. Other leagues may not see values this high.

Top-75 Stats-Based Pitching Prospects

It’s time for my latest computer based pitching prospects. In my last article, there was some confusion on how the rankings are to be used. Here’s a breakdown of what the rankings are and aren’t.

Are

  • A supplement to Eric’s and Kiley’s prospect rankings. This set utilizes stats, age, role, and some regression to find potential overlooked prospects before they start showing up on major prospect lists.

Aren’t

  • A complete list of every prospect. Some will be missed. I don’t care as I’m digging for one-offs. The most likely reason for not being on the list is they haven’t performed, not played much (major factor), or have graduated to the majors. Major league results are also not included.
  • The order doesn’t matter at all, at least to me. Why one person is #8 over some guy at #14 compared to other lists is irrelevant. These top prospects are already owned in most leagues. I feel the order only matters to desperate fan bases looking for some much-needed hope.

Estimating Weekly FAAB: Step One

A couple weekends ago, Dave Appelman asked my fellow writers and me what features we’d like to see available at RotoGraphs (more additions are in the works) and a FAAB (free agent acquisition budget) bid estimator was discussed. With so many leagues and so many bidding setups, I accepted the daunting challenge. I’m beginning to produce some limited usable results.

Before I go into the many inputs in FAAB bids such as declining budgets and absentee owners, I needed:

1. A way to measure owner seniment before the normal Sunday FAAB bids.

2. A reliable source of FAAB bids.

For the first source, I’d like to thank fellow RotoGraphs contributor, Al Melchior for pointing out that CBS Sportsline displays historic weekly ownership rates. Every host website will display ownership rates. What was important with this source is they have a ton of quick grab waiver wire leagues. As soon as a player bursts on the scene, owners can go pick them up off the wire. The ownership rates for these hot commodities immediately begin ticking up. These values are available but the bases need rounding a few times to collect them.
