Because that dumb ass Dwight has no post moves! He spun not away from the arm in his back but into Bargs chest and didn't even have a counter fake, drop step, or spin back. He's a joke, shooting. 30% on his post ups this year. Dwight's first step is gone, before he didn't need moves because he would simply use a quickness burst from point A to B that no one hardly could react to short of Pau in 09, Yao, or Perk
Bargs also is one of the best post defenders in the league for his career. His help d sucks, but his metrics for post defense have always been in the above average range. It just sucks he's doesn't play help d or rebound.
