The C's definitely beat Cleveland, which imploded, and Orlando was just too lazy the first couple of games and then too discombobulated. The LA/Phoenix series should've at least gone another game, and I'm still not sure how they got past Denver so easily, but I didn't see any of that series.
I don't believe any sport that makes a lot of money is completely clean, and the NBA is certainly no exception -- basketball is so fast and complicated and has such high scores that tampering with it is comparatively easy -- but it's still usually fun to watch. I enjoy the regular season more than the playoffs because the games are less important, so there's less to get bent out of shape over. The things they do and don't call, though, can be maddening.
Kobe guards Rondo not because he's particularly suited to it but because the refs will give Kobe star treatment that Rondo is at least a season away from, so Kobe can get away with a lot. Garnett never gets called for holding or pushing. Bynum can practically set up a tent in the paint without getting called for a three-second violation, and he and Gasol never get called for offensive goaltending. Perkins will get called for an illegal screen at least once per game, which is especially awkward because the rule is so vague that no commentator can explain it. (Ditto for the ridiculous Restricted Zone rule, which even the NBA can't explain.) Pierce and Kobe can usually draw fouls just by grimacing while making an awkward shot.
In this series, they're trying to make it even out. They call a lot of ticky-tack fouls but skip major calls. In the last game, the two teams got called for the exact same number of fouls, which isn't equitable (it makes a big difference what kinds of fouls are called, and on whom, and at what point in the game) but at least looks good on paper.
Davis and Perkins, on the C's, both had great defensive moments where they got called for fouls that didn't occur. Davis had a perfect, clean block, and Perkins did a hilarious I'm Not Touching You! job on a shot by Kobe where he
still got called for a foul.

And they wonder why he gets so many technical fouls.
