The dude he was guarding scored @ 38 points! The (2) best defensive plays on him were by JCL. I hope you were joking.
I mean, he fell asleep a couple of times, but in general made Johnson work his behind off for those points. And he was a steadying impact on offense and actually managed to hit some shots.
I don't think you should scapegoat individual players, but if you're going to do that, I'd say look elsewhere (Hill, poor Finke...)
