I would rather have Barnes than Delfino.
Then Barnes is really overrated on this board. Barnes has been complimented for his versatility in being able to play multiple positions, yet is a below average defender for the most part. Delfino is a better rebounder, defender, passer, and creator. Barnes anticipates certain things better and is an open shooter but thats about it.
Maybe it was just because he was on PHX and GSW, but his defensive EFFORT hasnt been good these past few years.
