"There’s a defensive tackle at USC named Jurrell Casey, and he’s the protypical nose [tackle]," Razzano said. "He’s like another Michael Carter, who we got in the fifth round in San Francisco – one of the all-time steals. I see he’s rated as the ninth-best defensive tackle. If they do a [mock] re-draft in a few years, he’ll be a top-seven pick."

Razzano showed me some tape of Casey from last year’s game against Cal, and the visual evidence was impressive.

"Watch him split the double-team here," Razzano said as Casey burst between the Bears’ center and left guard. "Look at that nasty explosiveness. I’m telling you, it’s [like the Pittsburgh Steelers’] Casey Hampton(notes). He has short-area quickness and enough of a motor to satisfy me. You have to realize, defensive linemen don’t all have great work ethic. That’s why they’re big. But [Jurrell Casey’s] a naturally explosive guy, and they’re hard to find."
