I assume you mean Joe Milton? He played in a grand total of 3 games last year and was 3/7 for 59 yards. All three of his completions came in a 52-0 game against Rutgers. On the season, he rushed 5 times for 16 yards. In his game against Wisconsin, he rushed twice for 6 yards, and had two passing attempts. One was intercepted.
On the other side of the the ball, Minnesota is trotting out Tanner Morgan, who threw for 3,000+ yards and 30 touchdowns, ending the season with with the 5th highest passer rating in the country behind Tua (1st round draft pick), Burrow (1st round draft pick), Hurts (2nd round draft pick), and Fields (proj. 1st round draft pick). He'll be throwing to Bateman (1,200 yards and 11 touchdowns) and CAB (350 yards and 5 touchdowns). When he hands the ball off, it's going to Ibrahim (600 yards, 7 touchdowns, 5.3 ypc) who was stuck splitting touches with the Big Ten's 3rd leading rusher behind Dobbins (playing in the NFL) and Taylor (playing the the NFL) last year in Smith. By the end of the season, Ibrahim looked like the better rusher.
Even if the front seven is young / inexperienced (it's not), Minnesota is returning two fantastic corners in St. Juste and Durr so Minnesota will likely be able to bring players in run support or spy him, if necessary.
There's a lot of reasons Minnesota should probably be favored in this game, the fact that I don't have them favored is 100% Michigan's raw talent, but 3-pt favorites on the road with a first-time starter QB on O, going up against this offense on D? No way.
