Marcus Mariota impressive in debut while Jameis Winston struggles

Number-one draft pick Jameis Winston threw an interception touchdown with the first pass of his NFL career with the Tampa Bay Buccaneers.

Going up against Heisman Trophy winner Marcus Mariota and the Tennessee Titans, Winston found cornerback Coty Sensabaugh with a risky effort, allowing the Titans cornerback to waltz into the endzone.

Mariota, who won the Heisman Trophy at Oregon last year while leading the Ducks to the national championship game, finished the first half with four touchdown passes, including one to Kendall Wright to open the scoring Sunday at Tampa's Raymond James Stadium.

Winston, the 2013 Heisman winner at Florida State while taking the Seminoles to a national title, completed only 6 of 12 passes with a 5-yard touchdown pass to Austin Seferian-Jenkins and two interceptions.

Mariota is the first rookie quarterback in NFL history to throw four touchdown passes in the first half of his debut.
