There is more than one way to say "Welcome to the NFL." Philadelphia Eagles defensive coordinator Juan Castillo's version just has a bit more spice.
"I don't know what I did," Cox told the Philadelphia Inquirer. "But I said, 'Yes, sir,' gave him no lip back, and I just kept going."
Defensive line coach Jim Washburn also got in on the action, coaching up Cox for not hustling during a drill.
"I know that's one thing Coach Washburn is going to do," Cox said. "He's going to get after me, and that keeps me motivated."
