Rondo + Bradley + Howard = NBA record low opponents PPG.
Interesting, it seems to me that KG and Howard are very complimentary players and Howard could make another year of KG reasonably successful. Howard can shut down post options while KG harasses big men with perimeter games. Offensively KG would not crowd Howard in the post. This may be the one circumstance where I would like to see KG for another year.
I suspect KG's cap hold would complicate matters, though we could take care of that before signing Howard.
