Don't get me wrong, Butler's D was impressive especially playing the minutes he did (I think 45 was his lowest for the series, and he did 48 a couple times). But LBJ averaging almost a triple double every game, even on somewhat extended minutes, is pretty far from "ineffective." Yeah he had to work harder for it, credit to Butler and Chicago's overall D. But his production didn't slip, and it didn't come at the expense of the rest of the team's numbers. You'd expect him to have to work harder and play more minutes in the playoffs in general, especially against a defensively minded team like the Bulls. Maybe it just says something about Lebron's game these days when we can talk about how him actually having to work for these kinds of performances is a sign of good D.
