It has been more than a month since the release of my "too early" Big Board for the 2016 NFL draft, a ranking that includes 2015 underclassmen. For this, I'll go a little deeper into each position group so you'll get an idea of more than 100 of the top NFL prospects for 2016. It goes without saying that these rankings are preliminary, as I have countless hours of evaluation still ahead for the 2016 class.
A couple of important notes about the rankings below:
• I've split them into seniors and underclassmen; it's important to have a baseline number of seniors because those players are certain to be a part of the 2016 NFL draft process (if they so choose).
• I won't go too heavy into actual scouting reports, as those are still works in progress.
With those parameters in mind, here's an early look at the top offensive line prospects -- tackles, guards and centers, 30 players in total -- in the 2016 draft class.
