Josh - Tougher call than most posters are giving credit for. Especially if this is a keeper league. Miguel Cabrera is three + years younger than Pujols. Its not crazy to think he out produces Pujols from here on out. However, Votto is a stud, and I'd like to see Hart produce this years numbers more than once. Cahill vs. Liriano (I guess slight edge to Liriano - he still hasnt lived up to the hype of his rookie season due to injury).
I would say Pujols, Votto, Liriano in a close one. Having said that, maybe you could ask for an upgrade over Hart and/or Cahill in this trade?
