Ehh, Michigan is different than those other teams.
When you look at Michigans starting 22.
On offense, only 1 player was lower than a 4*. It just so happens to be Zak Zinter who is their best OL lol but JJ and Donovan Edwards were both 5*
On defense, there's 4 players that are 3*. Mike Barrett, Mikey Sainristil (was recruited as a WR, switched to CB and makes big-time plays), Rod Moore, and Josh Wallace (transfer from UMASS).
So 3/4 of their starting 22 is Blue Chippers.
Michigan is just better than every school at identifying talent and knowing how to develop them. And when I say talent, I mean kids who are low 4*, 3*, and kids through the portal.
And that starts with Harbaugh. And it starts with him finding his staff that he trusts (Tim Drevno/Pep Hamilton. Josh Gattis. Don Brown.) Eventually backing off play-calling duties. Changing the S&C. And building and setting the culture within the program.
The "team" as Michigan likes to say, may be corny to a lot of folks, but it's what got them this Natty. Its a team dedicated to each other, that's full of seniors, who have been through the pain of losing multiple CFPs.
Harbaughs pedigree was better than Marios when he got hired by Michigan than Marios is when he got hired at Miami. And you can't compare the two. Jim has developed players at CFB and NFL. He's literally been successful at every stop from Univ. of San Diego to Stanford to SF to Michigan. Mario does not have that lol
Mario should not be trying to build his team right now like the way Michigan has the past 3-4 years. Cause Mario isn't the coach Harbuagh is and I don't think he has the same level of coaching staff as Michigan does (not strictly coordinators. I also mean position coaches, analysts, etc).
Ultimately, I do think Mario wants to run the program similar to what Harbaugh and Michigan stand for. A team full of hard-working, mentally tough, selfless players, that have been developed into high-level starters. Kids that tackle in open space. Kids who don't commit bonehead penalties. Kids who are disciplined in their scheme and assignment. A team that has leaders in every room. All while being NFL players at the next level. That team can be a team full of blue-chippers if he can land the right ones.
So yeah, Mario needs blue-chippers to make up for the deficiency that he and his staff lack in coaching right now. Will it always be that way? Who knows. Probably. It would take a lot of pride swallowing for Mario to back off his staff and let them do their thing and just deliver them whatever they need to succeed (more staffers, nutrition, different types of players etc).
If you want to get rid of Mario and find our Harbaugh cause you want an HC who can develop kids into NFL players consistently, good luck. Cause they don't make a whole lot of Harbaughs and they're rarely available for hire..
