This injury just locked him into his player option year for 18mill.
Before this , if his season was uneventful with the Bucks and was injury free , I actually think he would of left the money on the table and looked to go some where else to play for a contender.
Now that his body isn't holding up to the injury of 08/09 season , he'll take the cash or get REAL REAAAAAAALLLLLL LUCKY and get traded.
As for the Bucks -
They get to eat 18mill or get very very VERY lucky and get a trade partner for Redd's services.
