The argument: Glen Davis finished 4th in the Sixth Man of the Year voting. He slumped late in the year and into the playoffs, which in part was due to playing through pain; he battled tendinitis in his knee for most of the latter part of the season, but didn't take a rest until absolutely necessary due to team needs.
His 11.7 points and 5.4 rebounds per game are very respectable minutes, as are his 14.3 points and 6.7 rebounds per 36 minutes. In fact, only 50 players in the NBA averaged at least 14.3 points and 6.7 rebounds per 36 minutes, and 44.8% FG%.
In addition, he's got championship experience, and has had big moments in playoff games. He hustles on the court, and is versatile enough to play both inside and outside. A guy like that is definitely a top-10 player in most team's rotation's, and is worth more than a minimum contract.
I absolutely agree. My biggest problem with Big Baby is actually the tendinitis, that could be a recurring issue, especially since he puts a lot of weight and a lot of power on those knees. Hopefully he will be alright, but I wouldn't give him a long term deal.
Others have pointed out, that his role within the team changed, when Jeff Green came as a 6th man and a scorer, and that this was a problem for him. I don't think so. Big Baby has played plenty with Paul Pierce to play within that role.
I do believe, however, that his shot selection became worse, because of all the changes in the 2nd unit. In the end, he was the only bench player getting significant minutes all season long. And somehow everybody started giving the ball to him as the shot clock went down. You could say, that he took it upon himself, but he was also forced to take those shots. This should be helped by having a new tight 2nd unit playing together all season. So if this is the biggest problem with Big Baby, I believe that it will be solved.
