Because real fans hate baseball douchebags, no matter whose team they are on. JB is a talent, but there is something to be said when the GM of another team tells you they don't want you because the fans hate you.
JB could be like Ortiz, instead he is a douche. It appears this Management is trying to build a more respectable team which likely means less BS with umpires and other teams. I prefer that model. I let him sign elsewhere and collect the pick.
His stunt last spring commenting on 'they got a discount for my years of service now I want to get paid more' was fitting when karma crashed his season. His injuring himself trying to throw the oriole out at first, more karma. The guy doesnt play the right way enough.
