Then we have different definitions of leaving it behind better. He took over a program that went 21-17 in 3 years under Levine. And left with a 22-4 record after 2 years.He had a great initial season and then the next year wasn't as good. So he didn't leave them in a better place. He won 10 games a Texas too, took them to a Sugar Bowl.
Tom Herman has coached 8 years at 3 Different Schools. Only once did his team win more games than it did the prior season.
Took over after Strong at Texas. They were 16-21 under strong. He left with a 32-18 record. Once again it looks better on paper.
