Depends on who they're playing, very few teams have a PF/C combo that can expose them , Lakers, Grizzlies, Jazz, Wolves and maybe the Clippers (if DeAndre really continues to improve offensively). Don't think anyone in the east has the frontcourt to do it, so realistically the Lakers and Clippers are the only ones they might face in the playoffs that have the combo.
You need your PF and C to both be able to score, if only 1 can do it they swarm him and play off the one that is limited offensively.
