Nice article here from Rivals about LJ and Urban and the importance they place on the DL. Here's a snippet touching on the specific measurables they are looking for at DT and DE:
"At the [defensive] tackle position, you like a guy who's athletic. You like him to be about [6-foot-3] to be a 3-tech. You like a nose guard around 6-foot-1 because he's a leverage player," Johnson said. "I don't like guys really big, I like guys at 280 to 295 [pounds]. I really like an athlete who can run and get off of the football because that can change the position on the inside." - See more at:
