As far as I'm concerned, we need someone to take he pressure off Diggs and I don't think a rookie will do that. Out of these two, I prefer OBJ. I hear the diva stuff, but to me he was performing well before hurting his knee and quite frankly we have established culture and coaches, and if we want to go all the way we need talent. McDermott needs to be able to handle the diva guys at this point or we're not going to make it to the super bowl.
As far as Thomas, my concerns are not about the injuries per se, but how and when they occurred. Just seemed to me the one year he could have had surgery earlier in the offseason and it just seemed overall that he really didn't want to play once Payton retired. Just the way the coaches were tentative about when he would be available to play. Would be really suspicious about him just looking for a payday, which is much different than a diva attitude.
I think it makes sense for us to bring someone in during free agency as a weapon, if nothing else it is Beane's mantra to provide flexibility in the draft.
