Arguably the greatest quarterback in Red Raider history, Harrell started three seasons in Lubbock en route to a 28-11 record (2-1 in bowl games). He holds the NCAA record for career passing touchdowns with 134 and was the first player in NCAA history to post multiple 5,000-yard passing seasons. His senior season was, by far, his best, as he had the Red Raiders on the brink of a national championship appearance after a thrilling, last-second win over Texas in Lubbock. The championship hopes were dashed in a 65-21 loss to Oklahoma, but Harrell still found himself on All-American lists and earned various Player of the Year honors to go along with a Cotton Bowl appearance. His lack of success at the pro level shows how much Leach's system effected Harrell's success; but his toughness is well documented and Harrell found ways to lead Tech to levels of success they have rarely enjoyed.
9. Andy Dalton, TCU (2007-10): It was true in college and it is true today in the NFL, Andy Dalton's strength is his intangibles. Rarely have I ever had the pleasure of watching -- or knowing -- a better leader both on and off the football field. A four-year starter in Fort Worth, Dalton was undoubtedly surrounded by talent -- particularly a characteristically dominant Gary Patterson defense -- in two of TCU's most successful seasons in 2009 and 2010. But there is no question that Dalton deserves the bulk of credit for willing those Horned Frog squads to victory after victory. With a 42-8 record (only three loses after his freshman campaign), two Mountain West Conference Championships, three MVPs in three bowl wins and two undefeated regular seasons, Dalton is just a winner. That's why the Frogs recruited him and that's why the Cincinnati Bengals drafted him. He threw for at least 2,000 yards in each of his four seasons and was a two-time honorable mention All-American and a two-time MWC Player of the Year. He holds TCU records for wins, touchdown passes (71), passing yards (10,314) and completion percentage (61.6), among others.
