Letterman takes some good-natured jabs about deflated footballs, with Belichick responding in his trademark gruff uncle tone.
The irony, of course, is that no one in the actual sports journalism world would be able to ask these types of questions and make these types of insinuations without permanent expulsion from Patriot Way. Letterman circumvents all that, making for some good television.
With Letterman set to retire from late night, perhaps he can make a second career as a hard-hitting NFL investigative journalist. The Goodell sit-down would be epic.
