OK, with my keeper league team due at the end of the week, I have a bit of a logjam of young CFs and can only keep one. Points league, 12 teams, 40-man rosters, 25 active, unlimited minor leaguers (provided you field a fully active lineup), and power and average are weighted similarly, while SBs aren't huge, but not insignificant. Freeze teams are determined by point value for each player. Unused freeze points are used in a pre-draft waiver draft.

Here are the three, with keeper cost in points. Pick ONE. 

Austin Jackson  DET    459

Drew Stubbs   CIN       447

Chris Young     ARI       513

Their costs are very close, so it's really most about who do you think has the best year this year, and who would you rather have for the future? My team is built to win now, but also well-stocked with top future prospects for next year and beyond.
