4. Willy Korn, QB (2007)
Willy Korn was going to be the savior of the Clemson football program and the next Charlie Whitehurst when he stepped on campus in 2007.
Korn, a 4-star QB prospect, was as highly-touted as they come and absolutely fell in love with Clemson from the start.
Unfortunately, it never worked out. He never won the starting job on a full-time basis and ended up playing just three seasons with the Tigers.
During that time, he had just 66 total passing attempts, threw for 406 yards and three touchdowns to two interceptions.
