I don't want it to be Patricia either the backwards hat wearing chubby dude looks to me to be a defensive puppet of a great D mind in Belichick. And of the other 2 only one would not be an ex-BB assistant, who's assistants carry an awful record after the leave Foxboro.
Fat shamer. lol
I think the assistants not doing well is a bit overstated, as the sample size is tiny; so saying all future assistants will do the same doesn't hold any water. Mangini/Crennel/Weiss are all failures.
Bill Obrien hasn't done amazing, but the Texans have been crushed by a rash of injuries to key guys (JJ Watt every damn year; half their defense; Watson) over the past few years. And saddled with $70m Brock Osweiler there for a bit. Watson will likely help his fortunes considerably. They think enough of BO that they are currently trying to extend his contract.
Nick Saban, while poor at Miami--Miami is show in and of itself-- has been ridiculous at the college level.
McDaniels was not a success, but he only got 1.5 years to do anything. His biggest failure was at personnel. Where he was awful. He had no QB, which is his fault, having famously drafted Tebow. He was given too much control as a young coach. It'll help to not have to deal with that side, and to focus solely on running the team on the field. He also went in as the big swingin dick, when he wasn't. He's said since, that he's been "humbled" by that experience, and I think that won't be the case in the future.
There's good and bad. But that's to be expected. There's a lot that goes into the outcome, from owner, to GM picking players, to scouting, to having a QB etc that impacts a coaches success.
What you do know is that the guy won't have BB's ability to find those players to fit the system. You've gotta rely on the new GM to do that.
