My favorite Nick Mangold memory occurred in the summer of 2008, when he botched an exchange with his new quarterback and was instructed by then-coach Eric Mangini to run a penalty lap around the perimeter of the New York Jets' practice field at training camp.
The new quarterback was, of course, Brett Favre. There were some glitches because this was only their second practice together -- Favre had just arrived in a trade -- but the hard-driving Mangini wasn't about to make an exception just because the guilty parties happened to be a future Hall of Famer and a Pro Bowl center.
