I don't think this is a guarantee at all. He's a really good coach who has a method of running an entire program and doesn't seem to have any identifiable vices. If a coach could bring UNLV to relevance then his method should work at most places. He'll get Purdue to the mid of the Big 10 within three years. ( Two years ago they had 7 wins with 5 of those big 10) Purdue had zero Big 10 wins this year and were totally blown out several times. ( Notre Dame 66-7, Wisconsin 52-6, Ohio State 45-0, Illinois 66-0) He'll get 1-2 wins next year but more importantly, his teams won't quit and have no more 50 point losses. After that, it will depend on how much NIL they can generate.
