Glen Davis has a weight clause in his contract.

"The bonus is huge. I wouldn?t agree to it if it wasn?t attainable," Davis said.

Doc Rivers sees a difference in Davis' weight.

"He?s in the best shape he?s been in in training camp," Rivers said. "I don?t know if he?s more motivated. He?s more mature. All the young guys grow up, and I think they understand what you have to be to start camp and what you have to do to have a good season. Each year, guys learn stuff, and Baby each year has gotten better and better and more mature."
