Belichick will be on constant alert for any telltale signs that his team is letting up. Stuff like ... An unusually sloppy locker room, players not bussing their trays in the dining hall, not as many game tape viewings (or downloads) as usual, meetings breaking up a little earlier or players skipping extra treatment. Basically, anything that says his players are buying into the hype. You do not want to be the guy Belichick goes off on for doing any of the above. http://www.nfl.com/news/story/0ap30...triots-primed-for-perfection-in-2015-campaign
