That's a dumb argument. The reason Manu didn't regularly dominate playoffs series is the same reason why he never regularly dominate regular seasons: he played alongside Tim ing Duncan. You know, the guy that is probably one of the 5 best players of all-time. Kobe Bryant didn't completely take over, and became the team's best player regularly on playoffs series when he played alongside Shaq, either, tbh.
Oh, and to answer your question: outside of that championship winning run in '05 (you know, no biggie. As if any NBA player has one of those), and those two series you mentioned, you have Dallas and Suns in 2010 and an argument could be made for Dallas and OKC in 2014.
