I kind of already did in a previous thread on your coaching search (search my posts).
The posts I've seen in this thread post Malzahn in the shiniest light imaginable. In reality his incompetence and failure runs very deep. Did you guys know that Colby Smith, the 2021 OT that we just signed away from you guys after Pruitt was fired, is the first HS OT since 2017 or 2018 to sign with Auburn? Malzahn has absolutely decimated the OL situation at Auburn. And this is an "offensive minded" HC. Imagine that for a second.
Then I see things like: "he almost won a National Championship in 2013". That was 8 years ago, in his very first season, with Chizik's players (most notably the OL left over by Jeff Grimes who is now the OC at Baylor). Auburn also blew one of the biggest leads you'll see in "Championship Game" history in that game. The very next season Auburn was 8-5. Two years after almost winning the Championship, Auburn was 7-6 under Malzahn. How is that even possible? In reality, the Championship appearance in his very first season was a total fluke. You'll find with Malzahn that his best talent is tripping his way into "greatness", and then due to incompetence he not only can't build on any success, but he actually manages to completely tank it somehow.
Then I see: "he's beaten Saban three times!". Stuff like that means nothing once you consider how much he lost to everyone else that would be considered a "rival". And these weren't competitive games, they were blowouts. Beating Saban three times should mean that you have the capacity to compete with everyone - with Malzahn you'll find that he can somehow challenge Saban reasonably, but then subsequently he's 2-5 in Bowl games with losses to UCF and Minnesota - two teams playing with half the talent that Auburn fields, who basically dominated us. He's beaten Saban three times, but he lost to Will Muschamp this season - in year 8 he's losing to a coach at South Carolina who would go on to get fired. He also lost to Pruitt, and really, you guys were making a game out of it this year as well before Guarantano gift-wrapped us the game with that pick-6 in the redzone. Check his record against Georgia and LSU as well.
He has zero idea how to develop or utilize quarterbacks and his offense was a total novelty that has been figured out. He hasn't been able to evolve or adapt. All of the quarterbacks who had success at Auburn under him: Chris Todd, Cam Newton, Nick Marshall, Jarrett Stidham were transfers who were developed elsewhere or had prior coaching by someone else in a different system. Malzahn's HS signees at the position have been complete flops with zero development - and he's recruited "highly regarded" quarterbacks. Consider this: 2020 Auburn had a 5-star QB (Nix), two NFL-caliber receivers (Seth Williams & Schwartz), an absolute freak talent at RB (Tank Bigsby) and yet it produced the season that you just witnessed. A loss to South Carolina and a 27-6 beatdown to Georgia playing with a WALK-ON QB who was like 4th string on their depth chart.
