Looking at the draft.

“As far as interior offensive line class, the top end of it’s really good," Mayock said in a conference call on Monday.

Notre Dame guard Quenton Nelson is a likely top-10 pick and one of the safest players in the draft, and after Nelson, Mayock said there are seven interior linemen who project solidly to go in the top three rounds.
The top spot on our list is a no-brainer. Nelson is the best lineman in the draft, arguably the top lineman in the country, and the only offensive lineman in my Top 10 list (third on that list). I have raved about him throughout the season, and he should be a top-10 pick in the 2018 draft, if not a top-5. He plays with elite power, technique, and awareness. He has agility and balance in pass protection, and all the “nasty” you could ask for.
This would solidify our o-line and solve our power running game woes.
With all of the reaching that happen every year for qb's and that Nelson is a guard, this guy could be there at 13. At 6' 5" and 345 pounds he is described as mean.
