Lee has been good on defense but not great.
He has been awful on offense (besides a few decent midrange jumpers here and there).
He's a good player that hasn't been playing well. He will find his niche eventually. But with the way Terry and Barbosa can score, once AB comes back, he is the odd man out. I don't know if Doc and DA will want to trade him because of how he was recruited, but the value won't even be there.
His size is an asset and may find him playing time because our 3 other SG's are all undersized, but if Green ever gets going, you may see him and Pierce together at the 2/3 against bigger 2's.
I thought Lee would have a huge role with the team, but his struggles coupled with the surprising acquisition and great play of Barbosa and the eventual return of AB may turn him into a cheerleader more than anyone originally thought.
