Top 300 prospects for 2015 NFL draft

The 2015 NFL draft will finally arrive Thursday, and below we present our final prospect rankings for this class.

We have ranked players 1-300 based on their NFL potential, including scouting reports for the top 100. Included in each player's write-up are his position-specific traits (1-5, with 1 being the best) and his Scouts Inc. grade in parentheses.

Here is our ranking of the top 300 prospects for the 2015 NFL draft:

1. Jameis Winston, QB, Florida State (Grade: 97)

Mental makeup: 2
Accuracy: 1
Release/arm strength: 2
Pocket mobility: 2
What he brings: Winston is one of the best prospects we've evaluated the last 10 years at the skills that translate to the NFL level, including making pro-style reads, going through progressions and throwing with anticipatory accuracy. He is also a good on-field leader. The concern with him has to do with his off-field behavioral and maturity issues.
