As we all know, New England Patriots coach Bill Belichick can be as prickly as a cactus - and as huggable as one as well.
But if you can set aside your feelings for Belichick the person, there's no denying that Belichick the coach is one of the best to ever pace an NFL sideline. As head coach of the Patriots, he's won four Super Bowls and gone to two others. He keeps his players on his toes through detailed quizzes and is not above releasing a bottom-of-the-roster player to remind them not to get so comfortable that they don't handle their job.
