A couple of micro fracture surgeries and some back injuries. The guy missed something like 5 games in 4 years from 2005-08, and always played like his hair was on fire. So, come 2009, he just decided he needed to take a lot of days off? That's idiotic. Like bucklion said, it wasn't his fault our idiot front office gave him a contract when it was evident his body was breaking down. As for the Bynum comparison, totally baseless. Bynum was known to be lazy and a malcontent. You never heard a bad word about Sizemore from anyone.
For a 4 year period, he might have been my favorite Indian to watch play...ever. Unfortunately, he ends up another in a long line of Tribe "what coulda beens"...
