No one position has a bigger influence on a college football team's overall success than quarterback.
A star quarterback, surrounded by good talent, can turn a good team into an elite operation. Just ask Clemson, which won its first national title in 35 years with a huge assist from program-changing QB Deshaun Watson.
On the other hand, mediocre quarterbacking can keep a team from consistently reaching its potential. Although Les Miles managed to win a national title at LSU, his inability to find successful quarterbacks ultimately spelled doom for his coaching tenure in Baton Rouge.
