IMO, it is a huge deal. I'm pretty sure he's the only one on the team who failed the test. I may be wrong but I think we'd hear about the others too.
What they said.
Here's a sampling of NT's on NFL rosters. You can find this info here.
Kris Jenkins 360, Casey Hampton is 325, Wilfork 325, Pickett 340, Dvoracek 303, Ron Edwards 315, Ron Fields 314, Aubrayo Franklin 317, Kelly Gregg 315, Ogemdi Nwagbuo 303, Sione Pouha 325, B.J. Raji 337, Jay Ratliff 303, Bryan Robinson 304, Shaun Rogers 350, Ahtyba Rubin 330, Ian Scott 315, Paul Soliai 355, Kelly Talavou 350, Martin Tevaseu 310, Gabe Watson 329, Willie Williams 305, Jamal Williams 348 and Pat Williams 317.
Out of twenty four NT's six are within 10 pounds of 350. You were outright wrong about Wilfork and Pat Williams. So if you count 25% being common knowledge I'd have to disagree.
The Fridge was an athlete. He could slam dunk a basketball.
