Reporter: As a defensive coach, though, with all the rules that have been made the last few years, would Marino have thrown for far more yards [under the current rules]? If Marino was playing now, do you think he'd have thrown for 5,500 yards?
Belichick: "Yeah, I don't know. If if's and buts were candy and nuts, everyday would be Christmas. I don't know. I have no idea."
Reporter: Do those rules help though?
Belichick: "Which rules are you talking about?"
Reporter: The rules of not being able to hit quarterbacks, and how receivers you can't touch them further downfield.
Belichick: "Those rules have been in place for 15 years."
