Belichick started coaching in this league in 19 freaking 75 and McCarthy wasn't even a teenager yet. You think he hasn't made some mistakes a long the way to get where he is today? McCarthy has been in the league since the early 90's. That's a couple decades worth of experience difference. I think MM is every bit as good of a coach as Belichick the only difference being Belichick has made most of his mistakes and has had 20 more years to learn from them. MM has made mistakes, his teams have made mistakes, but largely has shown the ability to grow from those experiences. I expect him to do the same going forward.
I don't disagree with what you are saying at all. That being said, the reason I am comparing him to Belichick is as mentioned, people on this board always want to act like the Packers are the greatest, but as of now, they really are not, so I compared them to the modern version of the greatest.
Also the he has been coaching longer than MM argument does not hold water when I say the coaches who have been coaching for a shorter period of time than MM and have equaled his success are:
Pete Carroll
Sean Payton
Mike Tomlin
John Harbaugh
It works both ways. Look, don't get me wrong, TT, MM and Aaron have accomplished truly tremendous things and I am grateful for that. But the bottom line is there is a difference between being a SB contender and Playoff contender and since those folks took over the reigns, only one year were they ever truly a SB contender and that year they got bounced out in their first game. I am sorry but this is a team that should at the very least have been in one more SB during this tenure.
That being said here is to hoping they get it figured out and maybe we can actually reach a couple more SB's in the next 5 years which is what a team with this much talent should do.
