TCU got to the final 4 by being a great team in a mediocre conference. Michigan has better athletes at every position, faster, and more depth. I’m sure Sonny Dykes is a fine coach, but unless Michigan doesn’t even practice for a month the equation is already written, you just need to solve the variables at this point. And if by some miracle they get past Michigan ( they won’t ) UGA will eat them up like chopped liver.
I don't think the difference is really at the skill athletes, and TCU most definitely has better WR athletes/talent than Michigan, don't think that one is even close. Biggest difference is probably the line of scrimmage guys- and that's where the game is usually won and lost. Michigan had a really good OL last year- this years is better. Because: Olu Oluwatimi- the 2021 All-American & Rimington runner up center they got from Virginia to transfer in might just be the best center in CFB this year imo. He took an already really good OL from a year ago that returned 3 starters up to another level. And Michigan has really good depth at OL as well- best depth on the OL that they've had in the Harbaugh era.
And then on defense they have some dudes on that front. Mike Morris at EDGE is 6'6, 290 with a six pack and can
move for a guy his size- son of a former NFL player- just got them genetics. Mel Kiper has him on his big board in the 1st rd. Mazi Smith at DT is 6'3, 337 lbs., was a former 4* top 100 recruit, Kiper has him as the #4 DT and going in the 2nd rd. They have lot of guys they rotate on that DL, Kris Jenkins (6'3, 285 lbs) and Rayshaun Benny (6'4, 292 lbs) have been really solid but their pair of true frosh DT's have been really good. Mason Graham at 6'3, 317 has been a starter as a true frosh at DT and been dominant at times- made bunch of Freshman All-American 1st team lists. Then their true frosh #2 NT Kenneth Grant who backs up Mazi Smith is probably the freakiest dude they have on their DL- he's 6'4, 350+ and freakishly big and strong. And then the depth they have at EDGE is pretty impressive too. Eyabi Okie (6'5, 245 lbs., former 5* 'croot), Braiden McGregor (6'6, 270 lbs., former 4* top 100 overall 'croot), and Derrick Moore (6'3, 279 lbs., 4* former top 50 overall 'croot, UnderArmour HS All-Star MVP) - all get in that rotation and are dudes. They rotate lot of defensive tackles and EDGE guys and stay fresh and just kinda wear teams down in the 2nd half.
