For the moment, yes. At one point Bill Walsh was the only one running his offense too. I already saw more teams doing some of what we do last year. Next year it will be even more. Kansas runs complex offense if less off ball screening. A lot of it is that you can't run it without the right players, so you'll see more as more teams adapt.
Yep, some of the stuff other teams ran def resembled what UConn was running in 23. Painter even said he wanted to steal some stuff he saw on film for next year during pre-NC press. He knew it was different. If a team is good enough, others will take the stuff.
Hurley is at the forefront right now. Others will start to implement his stuff. The question will become who does it and how good they are at getting buy-in and if they can recruit the right players for it (to run the offense and the defense).
Everyone loves/ed UConn's offense in the tournament, for good reason. They put together three games well above their already best in the country offense, one on par, and two slightly below average for UConn (Illinois and Stetson).
However, the defense really isn't talked about enough, because it went up to silly levels of good during that postseason run. Bama was the worst defensive performance and it rated decently on a national standard. The next two games were Purdue and SDSU and both of those were better than the average Houston defensive game. The other three were just crushing defensive games.
Finding players who can/will/want to execute UConn's offense while being athletic enough to play that level of defense is outright absurd.
Painter and his staff got out-coached by Danny and his staff. We still had the better team but the coaching staff/scout was noticeably better for UConn.
I go back and forth on this. Painter did get out-coached but I'm not sure what he could do at that point in the season. The flaw they had was they never had a game plan without Edey, or to use Edey to free up other players. All season long they played one way and they won. UConn was just one team that style wouldn't work against. They had zero movement off ball and not enough players to be able to drive, but they didn't have it all year and never showed they could run it. Is it Painter's fault in terms of coaching, or recruiting? Their whole offense was predicated on getting it to Edey in the post and letting him score, or if he is doubled, kicking it out to let others take open shots by swinging it around to find the open shooter. They were a very good passing team but never showed all year the ability to shoot off the dribble, or off the screen. They never had the need to do so. UConn shut down option B and let Clingan slow option A. They had no option C.
I think Creighton would have beaten them also TBH. Kalkbrenner was probably the only other center to be able to defend Edey 1-1 and not be killed down low. Creighton's problem was their offense was too hot/cold.
All that said, I think Mullins would be fine at Purdue, but he would shine at UConn.
