During his college career at the University of Michigan, Howard set or tied five NCAA and 12 Wolverines records. He also led the Big Ten Conference in scoring with 138 points during the 1991 season on his way to winning the Heisman Trophy, Maxwell Award and Walter Camp Award, earning first-team All-American honors. Howard captured 85 percent of the first-place votes in balloting for the Heisman, the largest margin in history at that time. Howard also earned a bachelor's degree in communications in 1992. In 2011, he was inducted into the College Football Hall of Fame and he was honored as the inaugural Michigan Football Legend, a program honoring former players equivalent to a retired jersey number. Each Michigan player to wear Howard's No. 21 jersey was to wear a patch recognizing Howard, and dress at a locker bearing a plaque with his name and time of tenure at Michigan.
His most notable professional season was in 1996 for the Green Bay Packers. He led the NFL in punt returns (58), punt return yards (875), punt return average (15.1), and punt return touchdowns (3), while gaining 460 kickoff return yards and catching 13 passes for 95 yards. His 875 punt return yards were an NFL record, easily surpassing the old record of 692 yards set by Fulton Walker in 1985. During the 1996 NFL postseason, Howard had a punt return for a touchdown in a game between the Packers and the San Francisco 49ers, and 46-yard punt return that set up another score. However, he did have an odd blunder in the second half, in which he failed to come out of the locker room in time for the start of the third quarter. No one on the team noticed, so the Packers had only 10 men on the field for the second-half kickoff, with no one in the returner position. As a result, San Francisco ran down the field and recovered the kickoff, leading to a 49ers touchdown. Still, the Packers won the game and reached Super Bowl XXXI against the New England Patriots.
