We are now three weeks into college football season, and some of the nation's top teams and players are still awaiting their first true tests of 2014, but we've already seen high-level performances from big-name and below-the-radar players alike.
That hasn't caused too many big shifts in our prospect rankings, which still heavily factor in the preseason scouting evaluations we produced this summer, but there have been a few players who made big moves up the board.
Here is our latest ranking of the Top 32 prospects for the 2015 NFL draft.
(Notes: Underclassmen are noted with an asterisk, and the scouting write-ups will stay the same for each ranking update except in cases where new material is needed.)
1. Marcus Mariota, QB, Oregon Ducks (Grade: 95)*
6-foot-4, 224 pounds
Mariota is a dynamic athlete who puts stress on a defense with his mobility both as a runner and a thrower. He has above-average elusiveness and rare straight-line speed, reminiscent of Colin Kaepernick with his long stride. Mariota has a quick, compact, over-the-shoulder release with well-above-average arm strength, so he can make all the NFL throws. While he needs to become more consistently accurate, and I want to see him show continued progress with his footwork and balance within the pocket, I thought he played really well in the Ducks' big win over Michigan State; he showed good mental toughness in bouncing back from early mistakes. He has outstanding intangibles and a very good mental makeup.
