I will be shocked if Alex Rodriguez's 211 game suspension is upheld during the appeals process. I have no doubt that he is guilty, and the fact the others all agreed to their suspensions without appeal pretty much shows that baseball has concrete evidence.
The problem in the A-Rod situation is, Bud Selig seems to be stretching the boundaries of how long he can suspend him via the Joint Drug Prevention and Treatment Program. None of these men tested positive for a test. Selig is going back to past situations (ie. Anthony Galea) and what he deemed as "lack of cooperation" when talking to A-Rod in the past about allegations. Basically, he's trying to make an example out of him. My guess is, A-Rod's legal team is going to argue that his client is being unfairly targeted over the rest of the accused, that MLB has it out for him (remember how conveniently A-Rod's, and only A-Rod's, name was leaked from what was supposed to be a confidential list of players who failed tests during spring training before the program was put in place?), that you can't now try and punish for past situations because it's convenient to do so now, and that his punishment should be in line with the others tied to this.
My guess? 50 to 100 games, tops. You'll see him on the field sometime during the 2014 season.
