No, no he wouldn't have.
This silly notion that Cuz can play the 4 has to stop. Offensively, it would be fine because Cuz can hit the elbow jumper and is comfortable in a face-up game. But he'd flat out suck defensively at the 4. He JUST figured out how to defend the incredibly offensively inept Center position without getting into foul trouble. Now some we want him extending out and guarding the Love, LMA, Lee, Blake Griffins of the world? No thanks.
I'm not all that sure you understand basketball and how Boogie fits into team defense. He doesn't have a problem guarding players in the post and getting into foul trouble down on the block for the most part, against 4's or 5's in 1v1 situations.
Where do most of his issues come defensively?
A) Being the last line of defense when our perimeter guys repeatedly get blown by and you've got explosive guards coming straight at him. His lateral quickness does help him there though. More on that in a min.
B) Reaching and going for steals. That's more a pick your spots issue and maturity issue.
C) Guarding the pick & roll up top, however it was a nightmare attempting to do so with our guard core last year, especially IT who got rubbed off on every other screen he came across and more often than not simply quit on the play. What we didn't have when Boogie was put in pick & roll situations was a guy like Lopez sitting back ready to challenge and clean up at the rim. The worst part of JT's defensive game is rotating quickly and contesting/altering shots in help situations. None of our other 4's are tall enough to even pretend to fill that role.
The worry for Boogie guarding PF's on the perimeter would be 1) reaching and picking up cheap fouls on jumpers and b) is he quick enough laterally to cut off a PF off the dribble from 15-18 ft out? I say his lateral quickness is extremely underrated and this idea he can't at least do a decent job staying in front of a few perimeter PF's doesn't coincide with the lateral quickness he's shown in help situations nor his ability to be a league leader in charges taken, which requires lateral quickness and a good reading of the game.
But it's not just a question about can Boogie stay with a Blake type on the perimeter 15-18 ft out. In a team defensive situation, he's forcing Blake to the help, which would be Lopez. Or he's forcing him toward one of our SG's/SF's shading him outside. Many times it would be both if played correctly. If Cuz does get beat by a Blake or a Love, that's where the rotations come in, the staple of any good defensive team. Lopez slides over, weakside SF/SG rotates down, and so on. I'd however recommend Cuz play off a guy like Blake or Lee or Aldridge and
make them beat us from outside. That would be a nice change from the freeway we normally have going to the rim where it's either a layup or Boogie risking foul trouble as the last line of defense. Get a shotblocking 4 and Cuz many times
still would be the last line of defense as that defensive 4 would be farther out on the perimeter guarding his guy. That's more of a consistent foul risk than what he'd face as a PF with a guy like Lopez behind him doing the dirty work.
Is it ideal? No, but I never claimed that, just it'd be better than what we have, which is FGA after FGA right at the rim with Cuz being the last line of defense and being put in a position to regularly pick up fouls due to the mistakes or limits of others. What's better than that? Having a guy like Lopez be the last line of defense(freeing up Cuz to worry about offense more btw) while Cuz forces the weenie, jump shooting 4's to beat us from the outside while also giving him cover in pick & roll situations. That's a lower % chance of beating us. It's shots at the rim vs jumpers outside.
There's also the other side of the ball. Blake/Love/Lee would have to spend some time guarding Boogie. I'd pound the hell out of them inside. Cuz would eat just about every PF in this league alive aside from a guy like Ibaka. He treats Anthony Davis like I treat a double bacon cheeseburger. Demolish it, then sit back with a little grin on my face thinking "that wasn't so bad, I'd like some more of that".
There's always the question of, "how will other teams attempt to guard Boogie as a PF?" I'd pound them into oblivion and do what I can to make the league regret going small and soft.
If all that would "suck" to you, give me more of it. Give me a bowl of suck and cover it in more suck. Then sprinkle a little suck on top. That's far more enticing than what our front court currently offers.
P.S. Z-Bo is slow as hell and couldn't jump over his own headband, but does very well defensively year in, year out guarding PF's.
P.P.S. Boogie still considers himself a PF.
