By the way, here's a list of every quarterback to win a Superbowl between 1989 to 2021 and their college win percentage. Tom Brady (80%), Patrick Mahomes (41%), Nick Foles (45%), Peyton Manning (87%), Russell Wilson (60%), Joe Flacco (62%), Eli Manning (65%), Aaron Rodgers (69%), Drew Brees (65%), Ben Roethlisberger (71%), Brad Johnson (71%), Trent Dilfer (70%), Kurt Warner (67%), John Elway (47%), Brett Favre (64%), Troy Aikman (82%), Steve Young (81%), Mark Rypien (40%), Jeff Hostetler (74%), Joe Montanna (86%)
That list shows that outside of Peyton Manning, the last quarterback to win at least 85% of their college games and a Super Bowl was Joe Montanna in 1989, 32 years ago. And, even then, Montanna wasn't a full starter until his fifth year at Notre Dame, and his 85.7% win rate only barely qualifies. Meanwhile, you have four different Superbowl-winning quarterbacks who won between 40 and 50% of their college games, seven between 60 and 70%, and four between 70 and 80%.
So next time your favorite team is up to draft a quarterback in the first round, pray they choose one that didn't win too much in college.
