I think having it ready and using it for a handful of possessions is beneficial. Of course our defensive identity is man. But a quick zone look change causes other coach/team to reconfigure, on fly, new offense they will use to attack it. For years a lot of coaches changed up defenses with mades/misses. Look at Pitino, still one of the best technicians out there, he gives different looks throughout the game,.
No one is saying zone all the time is an answer for us, that's a Boeheim straw man. Just a couple times a game. Or next time an opposing coach goes 5 out offense and focuses on picking on Mahaney or our weak link for drive after drive to the rim, throw a 1-2-2 halfcourt or a 1-3-1 or 2-3 matchup out for a couple of possessions. I'm afraid of our guards getting posted up in tourney. I've already watched what Teddy Allen and Eric Ayala can do in an ISO. It is a philosophy of some old school coaches that zone or junk defenses are pointless. But Danny's won 2 championships in a row, so its honestly pointless to even make this post, but here we are lol.
