Among the offensive linemen, there are several offensive tackles who could be selected in the first round of the 2014 NFL draft, and some other intriguing talents who project to go in the middle to later rounds.

How does our board of O-linemen stack up? I've ranked them below and grouped them based on their round grade, and I've included the average number of linemen to go off the board in each round over the last five years. You'll also see the traits we study when evaluating linemen, and the teams that could be looking to take tackles, guards and centers in this year's draft.

First-round grades

1. Greg Robinson, T, Auburn (Grade: 97): The most dominant lineman at the point of attack that I've ever evaluated; exceptional athleticism for his size.
