Julian Edelman played quarterback at the College of San Mateo in 2006 where he threw for 1312 yards and 14 touchdowns while rushing for 1253 yards and 17 touchdowns. Pretty gaudy numbers. However his English teach didn't think this football thing would really take him that far.
To tell you the truth, the teacher isn't wrong. The percentage of people playing high school and then small college football making it into the NFL is damn small. Once in a while you have someone who makes it through, and Edelman is one of them.
After San Mateo, Edelman transferred to Kent State where he played QB again for 3 years. He was then drafted in the 7th round by New England and 2 Super Bowl's later, he's a bonafide superstar -- at receiver. Maybe that's why the English told him to pump the brakes, he had never seen him run a route before.
