I think my statement is tying into the HC thing too much when I was aiming that toward one specific statement about it being an offensive league, yet the latest example I can think of ( both of the SB teams) were defensive monsters instead of offensive powerhouses.
I'm taking umbrage with that statement more than needing an offensive head coach to win. It does indeed seem though that offensive HCs are more frequent.
When I say offensive league, I mean the rules favor offenses. In my opinion it's easier to sustain success on the offensive side of the ball than it is on the defensive side of the ball- if you have a good quarterback and playcaller.
Yes last year two great defenses were in the SB. Denver was middle of the pack offensively (mostly due to QB play) but Carolina led the NFL in points/game. And generally when you see a successful defense, you'll see them paired with an efficient offense. That doesn't mean and offense that puts up points or yards, but an offensive that controls the ball, controls the clock, doesn't turn the football over, and puts the team in a position to win the field position battle (i.e. Not Chip Kelly)
Every year people point to the Super Bowl Champ and say 'that's how you win a Championship!' There are multiple ways to win. It's just my opinion that I would hire an offensive coach if the decision were up to me because I believe you'll be as successful as the guy under center and you need to support him as best as you can with the right coaches.
