Who will have more than 15-20 fielding errors this year?
I am in a league that drafts players for specific categories where each category is a separate draft, and one of the categories is errors. This tends to be the most unpredictable category for me, since errors are dependent on playing time, pitching staffs, and official scorer opinions (as well as player ability). I usually just look at the league leaders for the past two years and assume that this year will be similar, but 2 of the top 3 last year were Braun and C.Guillen, who switched positions, and sometimes players just have bad fielding seasons (see A-Rod in 2006).
Right now, I see some top error men to be: H-Ram, M-Cab, Furcal, Betancourt, Encarnacion.
