Settle down. I don't really know why we're doing this. He won six championships as a head coach. Plenty of other "better" coaches with "elite QBs" haven't come close to that. They've won two at best and honestly, plenty of other teams would be happy to hold that distinction. He deserves more credit than you're giving him.
It's been three years, which included a 10-7 finish and a postseason run with a rookie QB. Basically, this year will make or break your argument post-Brady as at least this time, he's got both the horses in the coaching staff and will likely add horses in free agency as they improve the roster to get them closer to where they were in 2021.
I don't know why you take such glee crapping on a guy who is only three years removed from Brady. If 5 years had passed and there was nothing to show for it, you could make the argument. But the rest of us remember it how it actually happened, and I'm absolutely glad they hired him. You can be competitive year in and year out with an elite QB. You can't go on the run we were just on without a great coach.
