What we're seeing in this thread is that after Freeze and Malzahn there's a huge drop off.
Matt Campbell, while an excellent coach, has no ties to the southeast and that could be a problem on the recruiting trail. The next hire must recruit well to compete.
Luke Fickell, same thing. He's a Big Ten country guy. There are exceptions to the rule that aliens don't recruit the south well (Saban, Kiffin) but more times than not it's better to have a guy with southern ties (Smart, Ed O, Malzahn, Freeze, Fisher)
Tom Allen, I don't think he'd take it. He seems like a guy content being settled into a quaint little situation, but a good situation ala Chris Petersen and Gary Pattersen. He's from Indiana. I think he stays there.
Chadwell, Napier, and other up-and-comers... Sure, there's potential. Chadwell may be the next Urban Meyer, who knows, and he's from East Tennessee so that's intriguing but I need to see him do it with another quarterback to prove that he didn't just catch lightning in a bottle in 2020. He regressed at Charleston Southern - I'm not really holding that against him because people get better and that was 4 years ago but I do think he's got more to prove before getting a major P5 job. Napier also needs to show that he can do it with another QB, but I do like that he and Chadwell both played QB in college and have coaching QBs in their background.
