I... agree and disagree.
To say that Michigan doesn't outtalent teams and then proceed to go that half of the team has better talent compared to the opposition (the trenches) is a slight contradiction. The Patriots have had the honor of having three recent Wolverines on their defense and one on the offense and all of them were physically gifted individuals, without question.
The big reason why Michigan is winning now compared to prior, outside of hacking into their rivals servers and stealing practice footage of course, is that their players are extremely talented in the trenches AND well coached. They have a monstrous floor, but their ceiling stands and falls with the skill positions and their QB play. Outside of that, you can count bad Michigan games in the trenches on one hand. The problem is schematically and on the skill position.
Which is also why they haven't been able to win the big one. The position that gets you over the hump is the QB, unless you're Georgia and your entire team goes in the first three rounds of the draft. And Michigan hasn't had really elite QB play. Outside of that, stud team thats guaranteed to win 10 games minimum simply based on having elite coaching and fundamentals.
They're basically an extension of the 49ers when Harbaugh coached them. Mean on the O-Line and D-Line but QB play... ehhhhh.
