maybe I'm mistaken but it appears the Cavs "backup plan" is playing LeBron at the 5. (We can say Love is at the 5, but typically we've seen LeBron take the big such as Brook Lopez a cpl wks ago).
I don't doubt LBJ's ability to guard centers. Indeed I'm kinda psyched by it. It seems to me that DG & Cavs have decided that Warriors are best beat at their own game, with no real big. LBJ can certainly rebound like a center. So maybe no big deal.
But it is honestly super curious nobody is talking about this, and Griff essentially saying, No LeBron we're not getting a big, you're playing the 4, and the 5 in a pinch.
Given that LeBron is the greatest trump card in basketball I think it's a canny play, but still feel you need one more big because you really can't afford to wear LBJ down. His driving at the end of the game keys the offense (unless Kyrie can get better at finding others, like he did for that spurt in December.)
