Dabol, was given a lot of credit for developing Josh Allen, Allen was erratic accuracy wise coming out of college. And in year 1, he seemed to fix Daniel Jones and hence Jones got the big contract and made the playoffs and even won a game in the playoffs.
Then the wheels fell off with Jones. Partly because of injury and partly because Jones resorted back to who he is.
I was at the game when Devito carved up Rvera's team. And Devito isn't talented to say the least.
Logan Paulsen would in his own polite way imply that Dabol was too much (my language not his) for Del Rio to handle scheme wise, when he mapped out why this team struggled against them.
So in short, if Dabol went back to running an offense, he might not be bad at it. Sort of like Dan Quinn here, he's not per se always running that unit even though its his niche. He's had other offensive coordinators. He's switched on and off as far as running it.
As I pointed out, I don't feel that Whitt coordinated that hot of a defense last year but I don't put that on Quinn. When you are running a team, its hard to go full on to coordinating too, something has to give -- see Kingsbury in Arizona versus here.
