It's called him and this FO/organization being cheap and hiring a terrible, retread failed Raiders HC instead of paying a bit more money to hire halfway-decent, new and modern up-and-coming OC and DC after the 2021 season. Plus, I think taking Loomis' age in 2021 and even now into consideration, he was too old, maybe was uncertain or didnt know who to look for or didnt want to look for a decent replacement.
