Years ago Kole Conard and Tommy Rowlands were signed by the Jets and did a training camp. Neither even made the practice squad if I remember, probably the likely results for Coon.
I did find this part amusing:
The workouts, Konrad said, "weren't that big of a deal." He was a standout among linemen in conditioning drills, and while many other players were sucking wind, Konrad was wondering when the real work would start. After running the fastest 40-yard dash among the offensive linemen -- though Konrad didn't want to brag and declined to say how fast -- Jets assistant coach Bryan Cox told him to "chill out," Konrad said, because he was going to have to run 20 of them. Konrad shrugged his shoulders. "They give you plenty of time between them," he said.
