New England Patriots head coach Bill Belichick was his usual robotic, unforthcoming self in his guest appearance on the "Late Show with David Letterman" on Wednesday.
Letterman tried to get Belichick to address the "Deflategate" scandal, but Belichick wasn't taking the bait.
Belichick got a little looser later in the interview, sharing a laugh with Letterman about Tom Brady's age.
