I don't think this is Maybin's year yet, although he's a legit power threat he hasn't finished developing and there are still holes in his swing (outside pitches, I think.)
It looks like all these guys have speed. Gomez stole 30ish bases last season but is projected to hit for the worst AVG out of the four (.250-.260). Anderson is projected to do the same, but he hasn't done it in the majors yet. Randy Winn will give you 20 or so (he's getting old), but will probably hit for the best average (.290ish).
Looks to me like Anderson is the best choice as he's projected to hit for a better average than Gomez and steal more bases than Winn. The only thing is that he's not an established commodity yet.
Thanks for looking at my roster from before, check out this OF glut I now have: viewtopic.php?t=381074
