He's a Heisman Trophy winner, leader of the high-flying Oregon offense and now a potential No. 1 pick. But will Marcus Mariota be a franchise quarterback in the NFL or the next big draft bust?

As Mariota heads to the NFL, "FOX Sports Live" analysts Donovan McNabb and Joel Klatt break down what will help him at the next level, and what may hold him back, in the video above.

Donovan continues the discussion with Charissa Thompson and Bill Reiter, along with Oakland Raiders lineman Donald Penn, who shares his experience of what it's like to play with a mobile rookie QB.
