So here is the contract I'd offer.
A 4 years 32 million dollar base salary with a games played incentive.
If he playes 140 games in year one of the contract he gets a 2 millon dollar bonus with a 2 millon dollar bonus after year 2. The same bonus would carry over to year 2, 3, and 4. Making it potentially a 4 year 52 million dollar contract if he plays in 140 games all 4 years. He is worth the money if he is healthy.
Adversely if he does not play 140 games in a year he only gets his base salary of 8 million. The problem is going to be if he starts to play hurt again like he did in 07. I still like having him around when he is healthy, but if he is not healthy I don't want to waste so much money.
I still think he signs with the Braves though. Cross your fingers.
