Here are the rest.
Trevor Trout, D-lineman at USC. A back injury held him out of this season. Tough break. I've enjoyed talking to Trevor the last few years.
Mario Goodrich, safety, Clemson: He was part of Clemson's defense this year, played quite a bit. Had two picks.
Kamryn Babb, WR, Ohio State: Has had multiple knee injuries.
Cam Brown, DB, Ohio State: Started for a while at cornerback but now a backup.
Michael Thompson, DL/OL, Oklahoma. He switched to offense after a serious knee injury and then left OU. I'm not sure where he's playing now, either, but I believe it's at a lower level.
Dallas Craddieth, safety, Iowa: Career backup
Daniel Carson, DL, Texas: Entered the transfer portal
Ayodele Adeoye, LB, Texas: Has had several major injuries, also in the portal
Perkins has had the best career, by far, followed by Parker and Goodrich.
