Before an estimated television audience of 70 million people, Penn State upset the heavily favored Hurricanes 14–10 to win the national championship, forcing seven turnovers, including Pete Giftopoulus' game-sealing interception of Testaverde in the end zone in the game's final seconds. Led by Michael Irvin and new quarterback Steve Walsh, the 1987 Miami Hurricanes won the school's second national championship and completed its first undefeated varsity season. The season was highlighted by one of the most memorable games in the history of the Miami – Florida State rivalry. Trailing No. 4 Florida State 19–3 in the third quarter at Doak Campbell Stadium, the Hurricanes rallied to take a 26–19 lead late in the fourth quarter on a 73-yard touchdown pass from Walsh to Irvin. Florida State responded with a touchdown in the final minute, but Seminoles head coach Bobby Bowden opted to go for two points and the win rather than kick the extra-point for a tie, and Miami's Bubba McDowell broke up the conversion pass in the end zone to preserve the 26–25 victory. More than 60 players on the combined rosters for the game went on to play in the NFL. The 12–0 campaign was capped by a 20–14 win over the then-No. 1 Oklahoma Sooners in an Orange Bowl billed as "The Game of the Century." The win was Miami's third over Oklahoma in the last three seasons, accounting for Oklahoma's only losses during that time period. The Hurricanes had a then-school record 12 players from the 1987 team selected in the following spring's NFL Draft, including Irvin and Bennie Blades, but with Walsh returning in 1988, the team gained the number one ranking with a season-opening 31–0 shutout of then-No. 1 Florida State at the Orange Bowl. The following week, Miami scored 17 points in the final 5 minutes and 23 seconds to top No. 4 Michigan 31–30 at Michigan Stadium. Hopes of a repeat national championship were dashed, however, in the so-called "Catholics vs. Convicts" game, with Miami dropping an emotional 31–30 loss to eventual-national champion Notre Dame on a failed two-point conversion pass in the final minute. Johnson left the program in February 1989 to become the head coach of the NFL's Dallas Cowboys, ending his tenure at Miami with a 52–9 overall record and a 44–4 mark over his last four seasons. Despite having the support of students, players, and even the Miami police and fire departments, offensive coordinator Gary Stevens was bypassed for the head coaching job and athletic director Sam Jankovich chose Dennis Erickson of Washington State to succeed Jimmy Johnson instead.
