There are two front seven players I'd consider in the first round:
Baylor DT Siaki Ika
Clemson LB Trenton Simpson
Both of these players elevate our defense.
That said, we should focus heavily on IOL in this draft. I think we have to patch up OT in free agency. The interior offensive line (guard and center) group in this draft class is one of the deepest positions groups.
This post makes more sense here.
Ika next to Quinnen takes so much pressure off of our linebackers and edge players. I understand that he's a defensive lineman and we've picked so many of those in the first round, but we are once again pretty thin at DT and his ability to impact to run and pass would be huge for our defense.
We'll hopefully be picking towards the end of the first round, so it's a less premium draft selection. Always the chance a prospect like Ika slides into the second as well.

While on the topic of defensive line,
Auburn's Colby Wooden never really took off this year, but he is a better version of Micheal Clemons. It'd be nice to have two of that type of DL.
