"With Fisher being a top-5 draft pick — even possibly going No. 1 — all the coaches and scouts are looking at film," Keyton said. "So they're looking at me as well.
"I've gotten a couple phone calls from a few teams. But mainly, I've been working out and running to stay in shape so I'll be ready for mini-camps to start once the draft is over. If you're getting calls between now and when the draft comes, it means you're on team's (draft) boards. So anything can happen."
One team that could be Keyton's landing spot is the Cincinnati Bengals. Not only do the Bengals have a long history of drafting and signing CMU offensive linemen, but Keyton has a relationship with offensive line coach Paul Alexander.
"Paul Alexander knew me in high school," Keyton said. "He was at one of the camps I went to. It was the Midwest Offensive Line camp. That's where I first got to meet coach Alexander through coach (Greg) Sherwin, who was my offensive line coach."
Keyton has stood toe-to-toe with NFL-caliber players such as Michigan State's Jerel Worthy.
"Jerel's a great player, and once he knows the snap count, he's a very great player," Keyton said. "So you have to change up the snap counts on him, or it's going to be a long day."
Keyton blocked for Harman some during their CMU career — mostly early on when the two were redshirt sophomores.
"I think Darren definitely has a chance," Harman said. "You can't teach 6-3 and 300 pounds. That's an NFL body type. He probably just feels the same way, that he needs an opportunity to go somewhere to showcase what he can do. I think he's got a really good chance."
