No one can stop KD, but LBJ can be better defensively to give the Cavs a better shot. It's more about team defense anyway, but initial individual defense has to be good enough to allow your team defense to have an effect.
He can't be better defensively playing 45 mins a game
Yup touched on this in the Boston series.
You want him to get you near 30 ppg while being your #1 facilitator on offense while guarding a historically elite prolific & efficient scorer AND playing 45 out 48 mins? In his 14th season?
Unrealistic. That is a much taller task than anything Jordan Kobe Wade etc were asked to do. Jordan in particular was fortunate because Scottie could run the offense and D up whoever.
Bron can get short "breathers" whenever Iguodala comes in but youre still being unrealistic in what you're asking him to do. One or multiple areas will inevitably suffer. Last night: turnovers and spotty defense.
