The best chance to collude to beat the Warriors is through K. Leonard and San Antonio. I think financially they can get better this offseason than Cleveland.
Imagine if they signed Chris Paul and Paul Millsap (possible?). Then imagine the Celtics traded Avery Bradley to the Spurs for salary and a couple of firsts (crappy ones albeit).
Paul, Parker, Mills, Murray
Bradley, Green, Murray
Leonard, Anderson
Millsap, Gasol, Bertans
Aldridge, Gasol, Dedmon
