Former Bills QB Jim Kelly and former Jets QB Joe Namath went at each other in a hilarious promo video for the Bills-Jets game on Thursday night. No punches were held back here by either Hall of Famer.

Jim Kelly & Joe Namath know some rivalries never die.

The @nyjets & @buffalobills are ready to renew theirs. #TNF

It starts with Namath calling Kelly to tell him that one of his golf putts just went wide right, while Kelly clenches his teeth and says, “This better not be another field goal joke.”

Then, things escalate from there, and both of their daughters even get involved in the trash talking. It’s highly entertaining.
