Even after missing an entire season to recover from surgery, Cavs big man Andrew Bynum is feeling that his body isn’t up to it. He is only in his mid 20’s, but with a man of his size, the body can get old much faster. Now only 5 games into the new NBA season, he is considering giving it up. Bynum said “Retirement was a thought, it was a serious thought. It still is. It’s tough to enjoy the game because of how limited I am physically. I’m working through that. Every now and again I do think about retirement, It’s still career threatening. I’m a shell of myself on the court right now. I’m just struggling mentally.” Hit the jump for more.
