For the second straight year, Jon Gruden’s QB Camp series on ESPN is being filmed at ESPN Wide World of Sports Complex at Walt Disney World Resort. Oregon quarterback and reigning Heisman Trophy winner Marcus Mariota (pictured) appeared at the complex to train with the Super Bowl winning head coach on Sunday, March 15. This year, the series will also feature the last two Heisman Trophy-winning quarterbacks, as Jameis Winston (Florida State) is scheduled to appear in April.
