He is easily the best candidate available… and he is definitely not the reason the Bills lost last playoff game.. that was mostly Allen.. call him… interview him
McDermott's first year in Buffalo in 2017, he went 9-7 with Tyrod Taylor as his quarterback and made the playoffs. The Bills drafted Allen in 2018 and the rest is history. Could McDermott make the Dolphins relevant again? Sure he could but would the Dolphins end up being the same as the Bills...ALMOST but never quite enough? I'd bring him in for an interview. If nothing else ask him, why were you never able to get over the hump and see how he responds.
Love it from a different angle: this will be another great experiment showing the effect of QB vs HC. Belichick lost that battle with Brady — average win% without Brady while Brady wins a SB without Belichick. Let's see what happens with Allen and McDermott.
Oh man him taking Lamar to the Super Bowl would be pretty funny. If he wants a ready made contender, that's the team. But I think any team with an opening should line up to throw money at him.
The odds are that Buffalo will end up with a lesser coach, so good for Miami. I'd take McDermott over YET ANOTHER guy new to being a head coach, but he'd fit well with the Ravens or Steelers.
