Trey Burton is aware of the odds.
An undrafted rookie free agent from the University of Florida, Burton is looking to make an impression on the Philadelphia Eagles' coaching staff.
"I've always admired [the offense], ever since being at Florida," Burton told the Philadelphia Daily News. "Even before that, being in high school [when Kelly coached at Oregon] and just watching how they operate. I wanted to be a part of it."
Playing a number of offensive positions with the Gators in four seasons, Burton finished with 976 receiving yards, 720 rushing yards and 20 total touchdowns.
Listed at tight end, Burton believes he can contribute in a variety of ways.
"I mean you look at the roster, a lot of people play a bunch of different positions," Burton told the Daily News. "I know [Kelly] likes that and that's what I do."
The odds are long to earn a coveted roster spot. But he's going to compete like crazy against the players ahead of him.
"I'm not really worried about that," Burton said. "I'm just playing as hard as I can and investing in myself like Coach Kelly told us at the very beginning: 'Invest in yourself.' And whatever happens, happens."
