Will Jake Peavy's arm fall off

The Sox should tread slowly on the rehabilitation of Jake Peavy in my opinion.  They have this  guys locked up for 3 more years, possibly a 4th. Is him pitching in April really going to make the difference?  Jake's arm essentially fell off last year.....  If I could find a video of it I would, but I think it was too horrific for youtube to put on the internet. Nonetheless, I'm a big fan of Peavy's because I appreciate his effort and  guts. I love guys who push themselves to get back quicker, but White Sox management needs to protect their investment.  If Peavy can come back and pitch remotely close to how he pitched before he got hurt, the Sox will win the division by 10 games, but if he re-injures himself this race will be a nail biter all season.
