Lamar Jackson leapt over a loaded field of Heisman Trophy contenders early in the season and by the time he slowed down nobody could catch him.

The sensational sophomore quarterback became the first Louisville player to win the Heisman Trophy on Saturday night, beating out preseason favorite Deshaun Watson of Clemson despite some late-season struggles.

Baker Mayfield finished third and Oklahoma teammate and fellow finalist Dede Westbrook was fourth. Michigan's Jabrill Peppers was fifth.

Watson, who finished third in Heisman voting last year, led a stacked group of contenders entering thisi season that included five of the top seven vote-getters in 2015.

Jackson outdid them all in his first season as Louisville's full-time starter, accounting for 51 touchdowns and averaging 410 yards per game in total offense. He ultimately won going away, with 2,144 points to Watson's 1,524. By percentage of possible points received, Jackson's victory was the sixth largest in Heisman history, and he became the youngest winner at 19 years, 352 days.

Jackson is the first Heisman Trophy winner to play on a team that lost its last two games of the regular season since Tim Brown of Notre Dame in 1987. He's the first to enter the postseason without a chance to win the national title since Johnny Manziel of Texas A&M in 2012.

No matter. Jackson did so much before November it was difficult to deny him the award because of a couple of missteps at the end.

He provided a signature moment against Syracuse, hurdling a defender on his way into the end zone, and then played his best against Louisville's toughest competition.

In a romp over Florida State and a close loss at Clemson, Jackson threw for 511 yards, ran for 308 and accounted for eight touchdowns. After ripping apart Florida State in September, he earned the stamp of approval from his idol, former Virginia Tech and NFL star Mike Vick.

Jackson left that Oct. 1 game in Death Valley as a threat to run away with the Heisman, but losses to Houston and Kentucky, when he committed four turnovers, in late November provided an opportunity for others to sway voters.

Watson made the biggest surge, but ultimately fell short.

Jackson continues a recent trend of breakout stars winning the Heisman. He is the sixth player to win the award as either a redshirt freshman or sophomore, all since 2007, joining Manziel (redshirt freshman), Jameis Winston (redshirt freshman), Mark Ingram (sophomore), Sam Bradford (sophomore) and Tim Tebow (sophomore).

Jackson came to Louisville as a three-star recruit from Boynton Beach High School in Florida. Some colleges were not sold on him as a quarterback, but Jackson was such a dynamic talented Louisville coach Bobby Petrino altered his offense to accommodate Jackson's speed and elusiveness.

Jackson flashed brilliance as a freshman and showed what was to come in the Music City Bowl against Texas A&M. He had 453 total yards and led Louisville to a victory.

Still, with so many well-established stars from Watson and Mayfield to running backs Christian McCaffrey of Stanford, Dalvin Cook of Florida State and Leonard Fournette of LSU, Jackson entered the season without much fanfare.

Just the way he likes it.

Jackson spent this season adjusting to newfound fame, growing into the role of face of the team and trying to stay out of the spotlight. He said he cut down on trips to the mall to avoid the inevitable crowds he drew.

He is about to become even more popular. Especially back in Louisville, where he has another year before he can even consider his next big jump — to the NFL.
