Celtics reserve big man Glen Davis claims he'll be a different, more mature player this coming season.

"This is the year of finally hitting that line of maturity, of finally becoming that player that I knew I could be," Davis said.

"Throughout my career, my three years being here, it's been up and down. When I play, you've seen glimpses, like, 'Wow, this guy could start. Or come off the bench.' Glimpses up and down. But this is the year of Glen becoming that whole player that 10 years down the road, eight years down the road, will hopefully be an All-Star."

Davis is entering the final year of his two-year, $6.5 million contract.

"When you think about contract, that's when you really don't focus on what you need to focus on," he said. "I'm just trying to focus on helping my team get back to the Finals and winning it."
