I have to say I am impressed with Green so far this season. Since trading for him, I had lots of complaints. He could not post to save his life, not a great rebounder and mediocre defense. 2 years ago, playing alongside KG and PP, we were ready to label him as one of our future and carrying the torch, played very well the last half of the season. Last season he showed hope but very inconsistent at times when we needed him and we the fans wanted to trade him. This season, he showed up to play every game, posted well, defense slightly above average. He is improving all of the things I was criticizing him for.
If we do keep Rondo and Green (I'm in the don't trade them camp), we need to get those two help and ASAP. We need a real center (Zeller is doing fine since starting, so I think he should get increased minutes like 30ish mpg, and down Kelly's minutes, good offensive player but he isn't stopping anyone).
