Rondo's chemistry with the championship team members (from strongest to weakest):
1. Perk
2. KG
3. The Truth
4. Doc
5. Ray
PP and Doc are interesting. Doc and Rondo's clashes were probably more off the court than on the court, PP and Rondo's issues were more an on-court clashing of styles.
Yeah I think PP appreciated Rondo, even liked him, but didn't bond with him ala KG. I just think Paul was more arms-length about teammates -- especially considering he went through a lot of lean years and trades -- than the usual star.
