From what I've read, it's hard to find a sympathetic character in this story.
Arod: proven liar, egomaniac, cheater
MLB: inconsistent at best in their treatment of PED's, shady (purchasing evidence from a thief with a briefcase full of cash), self-serving
I don't know what he arbitrater was thinking. I don't see any precedent or justification for the 211 games or the 162 games that they pulled out of a hat.
I think Arod's lawyers will be able to make a good case in court. Of course, he is guilty of cheating--it's just the whole thing was handled poorly.
