I think the zone is going to perform at a high level this year. Prior to the exhibitions, I was really worried about Malachi because I'd heard defense wasn't really his thing. After the exhibitions, my mind has been put at ease. Crappy competition level aside, he appears to be learning the rotations at a pretty accelerated pace and his arms are everywhere. 6'6" is traditionally small for a Syracuse small forward but he makes up for it with more quickness than we typically have at the position and a near 7' wingspan. I think he's built for zone defense. On top of that, Roberson looks like a monster physically this year and has plenty of experience in the zone, Cooney's solid up top, and Gbinije's size is going to cause a lot of problems for guards. The only question mark I see is Coleman's ability to protect the rim. However, where Coleman falls short in shot blocking, compared to Rak, he gains points with his wide body and ability to push guys out of the paint, which Rak couldn't do.
Gbinije and Cooney would not be good m2m defenders against most guards, imo. Gbinije would struggle with the small, quick ones and Cooney might too. In m2m, Malachi could end up in a lot of post situations with bigger forwards, which would be no bueno. And Coleman would be in big trouble away from the rim. Roberson is really the only guy I see with better/same potential in m2m as zone.
On top of the personnel stuff, I think a functioning Boeheim zone does all of the things m2m can do. We can ratchet up the intensity and speed of the game by extending beyond the arc and trapping more, we can limit 3-pointers if they're killing us (Kenpom wrote an article about the effect of our zone on 3-point shooting), and teams that can pass well against the zone would pass just as well or better against our version of m2m, with the likely addition of more dribble penetration.
