Reply with the guys I inevitably left off. I felt it would be too much a homer move to include someone like Dylan Moore (2B/SS/OF) but when he started last year, he was $.
With my bench guys, in addition to position versatility and potential production, I want people who play nearly every day. Using FGDC for PA and ATC for wOBA:
Donovan: 539 PA, .324
Steer: 455, .309
Estrada: 574, .316
Morel: 447, .308
Berti: 357, .299
Rengifo: 448, .301
Donovan clearly comes out ahead in terms of versatility (i.e., five positions), highest projected wOBA, and second highest project PA. I like Estrada a lot too, but Donovan looks to me like the best overall bench player.
