he was only HC there for three years, not enough time to go through the entire cycle. He posted a 21-15 record. They made a bowl game every year (Indy, Cheeze It, Sun). What doomed him is that he set really high expectations for the '21 season only to start out 2-4. They ended up with a winning record but it was too late. Also note that '20 and '21 were COVID-affected.
He is a very presentable guy with a lot of charm and charisma. For a U like Duke, he fits in perfectly. If I was a university president looking to hire a HC from a Coordinator, I am not sure I'd look much further than Manny. I understand the other "finalist" was tOSU DC Jim Knowles. I mean, while JK looks great, Manny could be the cover in Play
