I think peeps are under-selling what the coming season's Celtics could do.
Kemba was not a good fit here. He will do better next to a big, true, star PG in SGA.
If you add Horford's IQ and leadership, and ball movement (the style he helps implement is retained even when he's on the bench), to a healthy J's combo, a healthy R. Will, more seasoned Romeo and Nesmith, excellent defense at PG position, this team can be poised to make a run to the finals next year.
