It’s pretty normal for a coach to be good at one school and not another. He was also pretty good his first HC job, and his second stop he went in fill rebuild mode after the first year. So it’s hard to gauge since he came to the job he wanted all along before finishing said rebuild. UNLV also hired from within, because they wanted to continue what TJ started.
I think UNLV hired Kruger because he played at UNLV and they hope some of his dad rubbed off on him. With all their recent coach turnover, they were looking for a coach who could be a 5-10 year guy. He's their Paul Rhoads.
If they were hoping to continue what TJ started it didn't happen because they are going to have about 10 new players in their roster next year.
