That's certainly coherent. If Maggs come back and plays well for three months, if those three months include playoffs, then it will be more valuable. However, this does not mean he could not be valuable in roto leagues if he performs well for three months. Right now my OF is VWells, Cliff Floyd, Kevin Mench and Jacque Jones. I'm ok with that, and enjoy having Maggs in the DL so that if in two months one of my players is not performing or if Cliff Floyd gets injured, I will be able to plug in, not just a passable player for the last three months, but Magglio Ordonez. This could very well be a difference maker in a 14 team league. Instead of Victor Diaz, I've got some possible big backup. If it was a H2H league, this possibility would be even more important, but its important in a roto league as well.
But to get back to the real question, is Maggs going to perform?
