Kind of hard for me to answer that, as I've never worked with him or been coached by him. I would say on the surface, he didn't deserve the job that he got when he was hired with the resume he had. But he's had some success here, he's a high energy guy, seems to be a smart guy, and I think he'd be able to parlay this job into a similar one.
When I look at coaches, I generally evaluate them by how they're perceived by their peers. D'Onofrio, for example. We all knew the guy was a flaming bag of dogchit, and when he got canned, the only people who'd talk to him was the boys and girls club of Kendall. Then he went to Houston, was awful there again (of course), and I don't believe he's working anywhere now. The coaching fraternity is loyal to a fault. Once you're "in", you've got to display serious retardation to be out. That's D'Onofrio. He's totally useless, and his peers recognize it. That's a schhitty coach. Pat Nix was the same way. These guys ALWAYS get other jobs....the bad ones get demotions (Shannon, Randy), the good ones get lateral jobs or promotions, and the REALLY terrible ones fade into oblivion and open a camp (Richt, Jon).
I believe Banda has done enough to parlay this job into an equivalent one. Similar to Todd Hartley. I don't think Banda would get a P5 DC job right now if he left, but he may get some consideration, taking into account his group's performance, his reputation, and the success Manny has had here with the defense. So, is Banda a great coach? Probably not. Is he ruining the program, like Pat Nix and Jon Richt did? No. But you can't have 10 Banda's on your coaching staff. You've got to have some established pedigree. I think that's what Manny was shooting for with the Enos hire. But overall, it's a pretty weak staff. Compared to what you see on the staff's of many of the top 20 programs, it's an underwhelming staff overall.
