Adams just so happened to be at the facility when the Lions were announcing a new eight-year 'megadeal' for receiver
"Actually, Calvin Johnson was the first person I saw when I walked into the facility," Adams told Detroitlions.com. "As a football fan, that was pretty cool to be able to meet him."
Adams (6-7, 323) has quick feet and moves well for a tackle of his size.
He's is the fifth-best tackle available in the draft, according to ESPN, but the National Football Post considers him the second-best tackle prospect behind USC's Matt Kalil.
ESPN draft analyst Todd McShay had the Lions selecting Adams with the 23rd pick in his latest mock draft.
Adams was named first-team all-Big Ten as a junior and he picked up second-team honors in 2011 playing in seven games. Adams was suspended for the first five games last season for his involvement in the tattoo scandal that rocked Ohio State.
Adams had a terrific Senior Bowl, but raised some eyebrows at the NFL Scouting Combine last month when he did only 19 reps on the bench press and ran 5.4 seconds in the 40-yard dash.
"I think as an offensive lineman it comes down to what you do on the field and the game tape, rather than how fast you can run the 40," he said. "When am I ever going to run 40 yards?"
Adams did 21 reps at his Pro Day and looked terrific in position drills, according to reports.
"For me, the combine was a place to go and see how it was, and if it wasn't as good as I wanted to be, I still had my Pro Day," Adams said. "The only thing I wasn't that happy with at the combine was my bench. I improved that my Pro Day, so I'm pretty fine with all of it now."
