I'm not sure about the HBP thing, he's a big guy and not very agile, he can get hit 20 times a season if he reaches 500 plate appearences (He usually doesn't). .370 is over his average but .350 or even .360 could be reasnoble.
His K rate will raise, the drop this year seems coincidental, same as always swstrike and swing rates for him. But he's been killer both away and against left handers. If you need power and get into the later picks he will be your guy, pick him on away trips and versus lefties and I say you'll get very good power rates with respectble on base percentege.
