I hate Purdue as much as the next guy but I believe that Brohm was a good coach. Here’s how I know that IU f&$&d up with its choice (besides offering a guy a head coaching duty down at the vending machine). Both brought on board same year. Allen actually had a leg up being here the prior year. Brohm takes Detp Detp Hazell’s guys and takes them to a bowl and wins it. Allen comes off a bowl year and finishes 5-7. Next season, 2018: same stuff. Finally Allen beats Brohm in 2019 and they were 4-7 and we were 7-4. And it took double OT. After that, I Allen could never beat the guy. Hell, when Brohm was at Louisville, it looked like Allen had never seen this offense before.
So, the cautionary tale here is do not under any circumstances hire a first time head coach and one that has to build a staff from scratch., “Systems” transfer well when you bring coaches with you from before.
It’s The Bill Mallory and Cignetti model. Yes, you bring your coaches but you bring the system you ran together, plug and play.
