Mel Kiper has Jameis Winston at No. 1 in his mock draft

"Analysis: The bottom line is Winston is the most advanced on-field quarterback in the draft, and while the Buccaneers have a nice set of weapons for an emerging quarterback to utilize there's little evidence they have a future franchise quarterback on the current roster. Questions about Winston's maturity and off-field decision-making are more than fair and could have him written off some draft boards if he can't convince teams he can be a franchise leader. But on the field you get a big, durable, mobile, strong-armed talent with a high football IQ and an ability to read, anticipate and process at a very high level what defenses are trying to do. I would not draft with him with the goal of starting him in Week 1 -- his 2014 season proved there's work to be done -- but if Winston realizes his potential, he's a possible superstar."

Kiper didn't have Winston in his top-15 at one point this year.
