He is what he is.
A great on ball defender. Limited offensive player (who is improving) Still lacking in size.
He is a piece of the team. He is not the savior. He is not the switch.
He, for right now, is a platoon SG. The platoon of him and Ray last year worked. A good mix of defense and offense. Two completely different players that forced defenses to adjust strategies.
And no, he is not a major trade piece right now. He still needs a longer stretch of this improved play without injuries. Until then, his trade value will likely be less then his on the court value.
