Bill Belicheck is a defensive coach that is smart enough to hire good assistants. He has never been a QB coach
He deserves credit. It was his decision to keep Tom Brady on their roster during his first few training camps in 2000 and 2001 if I recall (as stated in the Brady documentary), after being a sixth-round pick. They nearly cut him a couple different times before he became one of the best quarterbacks of our generation. He saw something in Brady and kept him on the roster.
The head coach usually has the final say on roster spots and the most important is always the quarterback position. Sure, he hired a lot of great assistants. And most of them usually failed as a head coach on other teams.
Bill O'Brien, to be fair, has had success in his first two seasons as head coach despite not having a good quarterback. Hopefully that will change this off-season. I expect the Texans to draft a quarterback in the first round, as well as signing a veteran. I don't expect Hoyer or Yates back next season. I would part ways with Tom Savage as well. He's never healthy enough to properly evaluate. We could, in theory, bring in three new quarterbacks this off-season.
I don't think Andy Reid or Bruce Arians are as great as they appear to be. Sure, I'd give them credit for being where they are. Both are solid head coaches. I would even call Andy Reid the greatest head coach in NFL History who has never won a Super Bowl before. He's like the Jerry Sloan or Rick Adelman of the NFL (for those hardcore NBA fans like me).
I want to see how good they'd be if they had Brian Hoyer at quarterback. Not former first or second overall picks who were highly touted entering their respective draft class. I doubt Reid or Arians would sniff the playoffs starting four different quarterbacks this season. Especially one as bad as Hoyer.
To be fair, I guess Bill O'Brien is the only head coach not smart enough to realize Brian Hoyer isn't a starting quarterback! So oh well. LOL, I guess it's all a moot point. But what I mean is that the head coach, if he's good, will target a capable quarterback and put them in position to succeed. Whether it's his own brilliance or he hires the right people to his coaching staff.
Win you win Super Bowl rings you deserve all the credit in the world. The components of how it happened shouldn't matter. That's what ruined the Dallas Cowboys way back in the day. Everybody in charge wanted the full credit for that success. Jerry Jones and Jimmy Johnson couldn't co-exist.
Bob McNair isn't an idiot. At least I hope not. After all of these years you'd think he'd have enough of this quarterback shuffle. We've been starting way too many mediocre quarterbacks in recent years!!!!! Worse than the Browns to be honest!!!!!!
If the Browns had J.J. Watt and we didn't, we'd flip places record wise...
