Agree on his smart use of his length, and size. He's also in better conditioning than last year. He was caught standing straight legged at times last year. This year he is properly in a defensive stance at all times on defense. His size allows him to help on D and recover to his man and contest. He doesn't blow by shooters like Danny. He doesn't bite on fakes. He doesn't loose track of his man off the ball. He boxes out his man properly. He's gain muscle and is stronger. Strong guys that like to post up can still back him down some, but he's sturdy enough to at least allow a helper to come in and help, instead of just being a straight up push (like Daye).
He's able to fight through screens, anticipates them and uses smart feet placement to go over them, without fouling the shooter on the recovery. His size is apparent when you are aware he's able to get back into the play relatively fast. To be honest, the young man is going to be a plus in games. Like they say, you can't teach size, and he's got that. He's been larger/longer than all bench players and some starters he's been up against. He looked larger than Ariza for example.
We are right to be excited. He's going to help, not hinder that bench. The lineup with him and Boban is an Xfactor TBH.
The stars in the league will give him trouble of course, but those guys will give trouble to anyone and only a DPOY like Kawhi can deal with them, and they will still get theirs, so overall we are fine.
