We usually play tight man to man, but will occasionally mix in a zone if we're having trouble and need a change-up (only a few times this year). We guard up tight on the perimeter and rely on length/shotblocking of both the man on the ball and helpers Tor rim protection if we get beat 1v1. We typically stay fairly tight to shooters on penetration to prevent kick-outs, but will dig and recover as needed.
For ball screens/PnR, it depends which big is in the game:
With Sanogo in the game, we hedge ball screens heading towards the middle of the court above the break hard with his man as the screener (or Karaban's). We're excellent in help and rotation and often completely cut off PnR penetration without giving up any advantage. We're very well practiced with the scheme and our guys know their roles well. The ball defender will go over the screen usually (with your personnel, against Arkansas went under). The ball defender will recover and then switch with Sanogo, using their height/length to prevent passing to the roll man while Sanogo retreats (with Jackson/Hawkins generally roving the passing lanes with their athleticism). If you involve a guard as the screener, we'll switch it. We can switch 1-3 reliably as they're all 6'5"-6'6" and can defend guards. We'll similarly switch off ball screens when advantageous to do so. We do occasionally mix up the look and will at times ice, play at the level, or drop with Sanogo as well, depending on matchup or just to confuse the ballhandler.
With Clingan in the game, we usually run drop coverage, as he is not quick or practiced enough to hedge well. The guard defender will do their best to go over the top and get back in front as Clingan slows the penetration. His massive size and length with good-for-his-size mobility allows him to stop penetration and usually also recover to the roll man once the guard gets back into position. Guys shoot very low %'s over him in the lane on mids/floaters. As with Sanogo, at times Clingan will hedge to throw in a different look.
We almost always guard in the post 1v1. Sanogo is a very good 1v1 post defender (especially against power bigs, you can't move him) and Clingan is an elite post defender.
The combination of tight off ball D, sticking to shooters, and preventing PnR penetration means we often give up very few assists and force a lot of 1v1 in undesirable areas (off the dribble 3s or midrange stuff over help). Miami will be able to make some stuff happen 1v1 compared to some teams due to guard talent, but it won't be premium looks. And missing those shots with your guards in the lane is death when our athletic wings rebound and go the other way looking for shooters.
