Should Bonzi go Bonzai??

Bonzi Wells, generally considered a fringe type of player on an NBA team, has exploded for a huge postseason for the Sacremento Kings. Interestingly enough, he will be a free agent next year. Wells is probably going to be way overpaid, just as Dexter Jackson was after he won Super Bowl MVP for the Buccaneers. So my question is, do these regular players who explode in the spotlight receive money that they don't quite deserve from their season long body of work?
