Mike Mayock has moved Marcus Mariota ahead of Jameis Winston on his draft board.

Winston has been widely considered the top prospect in the 2015 NFL Draft.

"I've been fighting with this thing all along," said Mayock. "There have been two issues for me with Winston. Number one is on the field. He threw 18 interceptions this year. On a team that arguably had the best talent in the country, he continued to put his team at a disadvantage almost weekly," Mayock said on NFL Network's "Path to the Draft" Wednesday. " ... Off the field, regardless of what did or didn't happen in that alleged rape, he continued a pattern of poor decisions throughout his career. The bottom line for me is, can you trust him off the field?

"As far as Mariota is concerned, the more tape that I've watched, the more I've appreciated what he's been asked to do in their version of the spread offense. He reads combination routes, takes tremendous care of the football, and he wins games. He's not a natural thrower, but in the correct scheme, I think he can be productive. I've been fighting this for a long time, and I think that's what I've come down on."
