He has a horrible rebounding rate, he is constantly beat in the paint, he has poor shot selection, poor form, low FG%, non existent shot blocker, he can't pass, and he's a total idiot.
Why would you want a player like that on your team?
JJJ is better I promise.
We need someone that shoots well, and can finish the break, someone who can spread the floor and pass over people. Even if Glen was amazing he is still undersized. Leon Powe is an example of a good undersized player, Glen Davis is an example of a bad one. With that being said I still wouldn't want Powe I want a 6'10 player who can block shots and finish the break. Glen is awful at both, and everything else.
