Another good one on ESPN As Tom Brady's injury showed last year, every NFL team needs a good backup plan at quarterback - ESPN Here's a blurb: The Patriots actually ensured that Cassel remained focused through a different method: trial under fire. Every so often, during the middle of a game week, Patriots coach Bill Belichick abruptly would pull Brady out of a team drill and insert Cassel into the lineup. The idea was to see how Cassel would react to being thrown into a surprising situation with all eyes on him. Cassel never embarrassed himself in those moments, but the impact of those tactics weren't lost on him, either. .......... Added Denver Broncos coach and former New England offensive coordinator Josh McDaniels: "It would piss Tom off every time we did it, but Bill would just say we have to get Matt ready. When you put that kind of pressure on a guy, it only takes one time for him to go into a huddle and humiliate himself by not knowing what he's supposed to do. I've been there when it's happened and the players don't forget it. The last thing you want is for your team to be looking at the backup and thinking, 'We can't win with this guy.' That's why it's vital to keep those players focused."
