All three came here, having never been a head coach anywhere. But the last head coach with head coaching experience at the college level was Chaump. Pruett was a HS head coach. Doesn't matter, I guess. I thought it was interesting.
As pointed out already, Snyder's tenure didn't benefit from good timing (probation, new conference, team on a downward trajectory). That said, he didn't prove to be very good. He didn't improve things, though. His best season, his last, needed a bowl win to be over 500.
Holliday had several good seasons, including one conference championship. His best years were the middle years (2013 to 2015) with the championship in 2014. His teams were a little worse after those years. Cato was hard to replace at QB. Doc seemed to have had difficulty over the years against Western KY, Middle Tenn, and Ohio. I felt like before and after Cato, his teams underperformed. Rumors abounded of internal friction with players and coaches alike. His last season ended with three straight losses and a huge team fight in December that spilled out of the Shewey building onto the sidewalk along 3rd Avenue. Many passersby called 911. To this day, I don't know how that was kept under wraps.
Huff was a breath of fresh air and he's had some of the biggest wins (Navy, Notre Dame, Va Tech) and tight games against NC State. Had Doc stayed, the game against Navy would have been a lot closer if not a loss. Notre Dame for sure is a loss with Doc. But, Huff's teams have been inconsistent. We've lost games we had no business losing. We've lost OT games. We've had FCS schools push us around. We still have problems with mobile QBs. There is zero transparency even after a game. I understand why you don't mention that a player is out, but when a player has clearly not played, it's still not addressed. Rumors of him being connected with other coaching searches started somewhere and are baffling since he's not won a conference championship yet. The divisional championship is the best he's done. In my opinion, he's not ready for an elevation to a bigger program yet. But, I've been pleased this season. Not overly so, as our wins have been close. Until beating JMU, exactly zero of our wins have come over teams that have a current winning record. Some had a winning record when we beat them, but none ended up with winning seasons. That reeks of paper tiger. That said, I say we extend him to see what our new OC can do.
