Jeremiah Owusu-Koramoah would be an excellent fit imo. The guy flies all over the field, can rush the QB off of the edge, can drop into coverage even against a WR, is a sure tackler, and has good instincts against the run. He's listed at 6'1" and 216lbs, though I believe he's playing more around the low 220's this year, and could easily add a few more pounds to his frame without any hindrance. He's slotting anywhere between Mid 1st to Mid 2nd right now. He's been making plays all year for the Irish.
