Just his answer (of which I'll post a transcribed snippet) shows how much knowledge Belichick has in his pinky finger over most people, even other professional NFL or CFB coaches. Dude's just pulling this shit from memory out of thin air to a random question related to long snapping.
"I think long snapping, to me, changed in the mid-80s, and really the key guy in that was [Steve] DeOssie, in my opinion because Steve was the first center that really, truly allowed a spread punt formation against all-out rush. Prior to that, teams would generally pull. First of all, there wasn't that many gunners, but when teams started using gunners, they would pull one in and kick away from the free guy on the back side, and that was kind of the idea that protection was not to let the snapper block against a nine-man rush with a split player. The return team would have one guy on the gun or the split, and one guy returns, so you got nine guys rushing against essentially the punter who wasn't a blocker or the split guy who wasn't a blocker and the snapper who really wasn't a blocker, so it was nine on eight, and the idea was to block the most dangerous eight and let the ninth guy go and punt away from him, and then when the Cowboys went to spread punt and then the Cardinals followed that pretty quickly, and they kept two gunners split, and the snapper blocked a guy, then that created an eight on eight situation but put a lot of pressure on the snapper to deliver the ball 15 yards deep on the money and still block a good rusher offsetting and the A-gap."
