I know what you're saying. But I think owners wouldn't necessarily be into him from a marketing standpoint. I definitely think they would catch a lot of flack from their football people. Especially since in this era of NFL parity, almost any team can really compete for the Vince Lombardi trophy.
I definitely think the guy has serious athletic ability. He was an NCAA wrestling national champ, right? But his absence from any kind of organized football since high school is a huge strike against him. I think a route like the Arena league, the CFL or NFL Europe would be the most likely scenario for him before he plays a single down in the NFL. Could he get signed and get invited to an NFL training camp? Possibly, but I would be really surprised to see him make any team's roster.
Now, upon looking at the article, I'm even more unsure about the guy. He'd most likely play DE. Honestly, I think that may be more of a skill position than someone like him is ready for. He would really need to work on his footwork in a big way. There's also a lot more to that position than just pass rushing. It's about reading the offense, and trying to figure out pass versus run. I definitely don't think he'd be a serious pass rush threat to top flight O linemen like Runyon, Pace, Turley or Ogden. I think if he were lighter and faster, he might have more options in playing LB, but he'd need to shed like 30 odd pounds for that.
