To my eyes I see that Smart moves on the court with the ball like Derek Harper ( glides slow and deliberate ) and is a thief like Derek on defense but another observation is that he may play an overall game more in the line of Rod Strickland.
Rod played strong and often backed down his opponent. He could rebound, and was a very good assist man without being overly flashy. Never was the best shooter but did have the attitude to lead and give a team some identity.
A mix of Rod and Derek would be a fun player to watch, these two guys were both very underrated.
