Correct me if I am wrong but Grant had an injury early in his career that kind of pushed him back. I remember there was a lot of hype around him. I believe he was around for the old freshman football days, correct? I remember people raving about Grant's arm strength and how he could throw the ball a mile. I believe his injury kind of caused him to be a little affraid. He was from Frazier home town.
Also, Mickey Joseph was a star recruit. I remember being 8 years old and people saying "we got Mickey" and everyone believed he was going to be the next great husker QB.
I'll never forget the 1990 Baylor game and Grant & Joseph were splitting QB duties and Corso said at half time of that game, "when your playing 2 QBs at the same time, it means you don't have a good enough QB to win the Job". That stuck with me until this day and seems pretty accurate.
