The top-rated quarterback in Michigan's 2018 recruiting class is officially a Wolverine.

Joe Milton, a four-star passer from Orlando, signed his letter of intent on Wednesday morning during the first day of the early signing period.

Milton, a 6-foot-5, 230-pounder, plans to enroll early and be a participant in spring drills. Milton is one of two quarterbacks who committed to the 2018 class. The other, three-star passer Kevin Doyle, says he'll sign in February.

The No. 173-ranked player in the 2018 class and No. 7-ranked pro-style quarterback, Milton was known in recruiting circles for his raw ability and superior arm strength.

As a senior last season, he threw for 1,317 yards, 10 touchdowns and six interceptions. He also rushed for 262 yards and five TDs.

"Milton is everything coach Harbaugh has ever wanted. Harbaugh loves alphas. He loves guys who aren't afraid to get into a fist fight," noted quarterback coaching guru Steve Clarkson said in an MGoBlue release. "With Joe, he's going to go in, take the curriculum, break it down and immerse (Milton) in it. This is absolutely, 100 percent Harbaugh's type of kid. It's a perfect match."

As of now, Michigan has four signed scholarship quarterbacks for 2018: Brandon Peters, Dylan McCaffrey, Shea Patterson and Milton. Doyle would make five.

While Milton will have the chance to compete and train with U-M throughout 2018, he was not viewed as a no-doubt year-one player. Meaning he'll likely need some time to develop within the system.

Harbaugh has yet to allow a true freshman to take a snap at quarterback during his three years at Michigan.

“He's kind of the microcosm of the class," 247sports' Steve Lorenz told the Free Press this week. "He’s not a Year 1 guy. But he has the ceiling to be, in my opinion, a superstar if he can reach it. And that’s the question. You take a high ceiling in Milton and then a high floor guy in Doyle – a guy who had an excellent senior season playing against great competition."
