Michigan’s Cornerbacks Then and Now: Why the 2023 Title Secondary Closed Games, and Why This One Just Lost One

Michigan did not lose to Iowa because the offense could not move the ball. The Wolverines outgained the Hawkeyes and led 19-14 with under two minutes left. They lost because the cornerback room made the two plays a championship secondary is built not to make.

That is the gap between the 2023 national championship corners and the group wearing those spots now.

What the 2023 corners actually were

The title team allowed 10.4 points a game, No. 1 in the country. The secondary was the reason opponents could not throw their way out of a hole.

Will Johnson was the outside corner. In 2023 he had four interceptions and a pick-six, including one against Ohio State and one on the first play of the second half in the national championship against Washington. He was a second-round NFL pick. Mike Sainristil, a converted receiver playing nickel, was the closer. He intercepted Michael Penix Jr. on fourth down late in the 34-13 title win and took it the other way. Jim Harbaugh’s line after that game still fits: when a play needed to be made, Sainristil made it, and Johnson made it.

Sainristil had come back for a fifth year for one reason. “Let’s put everything into this last season. Let’s put everything into winning a national championship,” he said that spring. After the Big Ten title he put it more simply: “This is what we came back for.” After the championship pick he said he could not breathe from the moment he caught it until ten minutes later.

Jesse Minter’s defense did not ask those corners to be heroes every snap. It changed the picture, rushed the quarterback, and trusted Johnson and Sainristil to win the one-on-one when the ball had to come out. They did. No drama after the whistle. No lost fade with the season on the line.

What happened on September 26, 2026

Iowa won 20-19 at Michigan Stadium on the final play. The corners were in the middle of both kills.

Zeke Berry, a fifth-year senior who was on the 2023 roster, had a good coverage day. He was targeted seven times and allowed three catches for 15 yards, with two pass breakups. Then, after an incompletion on third-and-12, he shoved Tony Diaz out of bounds. Fifteen yards. First down. Iowa was no longer looking at fourth-and-long from its own 40.

Safety Rod Moore, who played on the title team, did not dress it up. “He’s an old enough guy to understand that’s a stupid penalty.” Kyle Whittingham called the day’s flags excessive: eight for 75 yards, “a couple of really costly ones, particularly on that last drive.”

Four plays later, Smith Snowden was in press coverage on Reece Vander Zee with two seconds left and Iowa at the 16. His back was to the quarterback. Hank Brown threw the back-shoulder fade. Snowden did not see the ball until it was in Vander Zee’s hands. Touchdown. Iowa 20, Michigan 19.

Brown said the pre-snap picture was exactly what he wanted: corners pressed, two safeties. The 2023 defense lived on taking that picture away. This one handed it over.

The comparison

Berry is the painful part of the comparison. He was in the building in 2023. He watched Johnson and Sainristil close the Washington game without a shove after the whistle. Three years later he is the veteran who did the thing that room did not do.

Why the standard dropped

It is not that Michigan forgot how to coach cover men. Minter is gone. Johnson is in the NFL. Sainristil is in the NFL. The scheme can still call press man. The players who made press man safe are not here.

Whittingham and Hill have said they want the 2023 defensive identity: multiple fronts, man coverage, pressure. Identity is not the same as the players. A championship corner wins the rep and then walks away. A corner who wins seven targets and then shoves a receiver has done the hard part and thrown it out.

Fan reaction after the Iowa game was ugly, and some of it was fair. One line that traveled: Berry should never have put his hands on Diaz after the ball was dead. Snowden’s alignment on the last snap is a coaching question too. Press with no cushion, two seconds left, Iowa needing the end zone, is a bet Johnson’s era did not have to make because the quarterback was already uncomfortable.

What this room has to become

Michigan does not need another Sainristil by November. It needs the habits that made Sainristil and Johnson trustworthy.

• No hands after the whistle. Berry is old enough. Moore already said so.
• Eyes on the quarterback when the ball has to travel 16 yards and the game is over if it falls incomplete.
• A picture the quarterback does not want. Brown got the look he expected. That cannot be the late-game default.
• A second corner who can survive a bracket. If Snowden is the boundary answer, the next fade against a better quarterback ends the same way.

Sainristil’s standard, from the spring before the title, still applies: “When freshmen come, I want them to say, ‘I want to be like Mikey Sainristil.’” Right now the tape freshmen will study is a shove and a lost fade.

The 2023 corners did not make Michigan a champion by themselves. They made sure the championship was not given back in the last two minutes. That is the job. Berry and Snowden had it against Iowa. They gave it away. Until that room plays the next close game the way Johnson and Sainristil played Washington, Michigan is one penalty and one fade from the same ending.
