They are pretty much doing EXACTLY what the Mavs did in 11. He didn't choke against Dallas like people want to say and believe. They took his strengths away, and outside of Wade, no one consistently stepped up to help, plus they had no way to consistently contain Dirk on defense. San Antonio is doing the same, in taking his strengths away. So far though, on defense the problem has been that the Spurs have been shooting lights out. I'm curious to see that when Miami makes some adjustments, and those 3's stop falling, if anyone can carry the team the way Dirk did for the Mavs. I think Miami is equipped to keep Parker from being that guy, as defense on perimeter players seem to be their specialty. They are good at taking away strengths from guards, but big men can really hurt them. Duncan is the guy who needs to step up for that purpose IMO.
