If we did get Josh Smith we'd essentially have to make him a Lebron prototype taking the majority of his shots around the rim.
He just cannot shoot. His stats are almost identical to his rookie season. The difference is when he was a rookie and 2nd/3rd year player, the majority of his shots were around the rim and in the paint- he'd get more offensive rebounds and more putbacks.
He's basically gotten much better as a player but his efficiency has dropped terribly because of his shot selection. I always had no idea why Larry Drew let him take so many jumpshots...may be to let Al Horford have space in the paint but it just didn't make sense.
Smith is like Dwight Howard but he's shooting jumpshots.
If we can get him to stay in the paint or even put him at center it could work. Make him rebound and get putbacks/easy looks from Rondo.
Anyway, here's his jumpshooting stats over his career. Just gastly...
http://hoopdata.com/player.aspx?name=Josh%20SmithI really don't know what he'd bring to the team unless we keep him as a KG replacement without the jumpshot and more finishing/strength around the rim. His defense and basket protection is good but his defensive awareness and help still need fixing. It would be great to have KG to guide him for a season or two. I guess he can sprint the floor with Green and Rondo which would be a high flyers club.
