On October 1st 1977, the 5th ranked Texas A&M Aggies made a rare trip north of the Mason Dixon Line to play the 3rd ranked Wolverines.
Michigan had started the season ranked #1 but they had been so unimpressive in beating Duke 21-9 and Navy 14-7 that they were demoted to third. Texas A&M was coming into Ann Arbor after an impressive win against Texas Tech in Lubbock. Most everyone expected Rick Leach's Wolverines to get rolled. It did not quite happen that way.
Michigan led 7-3 at halftime. They came out of the tunnel in the second half and produced 34 unanswered points to win 41-3. Of course WolverineHistorian has highlights on YouTube: 1st Half and 2nd Half.
