i might be a homer of kanter, but i'd like us to rebuilt with a front court of kanter and favors and millsap coming of the bench. we should realy use jefferson and harris for a solid starter point guard and a wing.
but you still don't get it. kanter has solid overall athleticizm. jumping high and blocking shots doesn't make you a great defender. it also takes thoughness, hustle, a big body and intelligence to become a good defender. the willingness, the awareness. kanter was described as a solid defender with his intelligence and i think he could become a solid defender in this league, believe me, he will be far better than boozer or memo on this side of the floor. next to favors, they might become a solid duo that can play both, defense and offense.
there are examples where over-athletic players seem to be thin and get overpowered by bigger players. also players that can leap like the hell but still not block a shot (like griffin as an example). you need also timing to be a blocking presence and there are defenders that aren't over-athletic but are solid defenders, like duncan, garnett, horford, noah and so on... don't think that the leaping ability alone is enough to play defense. for sure, athleticizm and a long wingspan might be attractive but it's still not enough. you also have to learn to play without foul trouble and so on... three highlight blocks doesn't make you a great defender.
