Patrick Mahomes and the Kansas City Chiefs will compete against the San Francisco 49ers on Sunday for the first time since beating them in the Super Bowl last February.

Speaking of Super Bowls, the Chiefs quarterback spent some time Saturday chatting with the only quarterback to ever beat him in the championship game: Tom Brady. The interview aired during FOX’s pregame show and was fun to watch for NFL fans who got the chance to hear two of the best quarterbacks to ever play the game talk shop.

A funny moment came when Brady brought up Mahomes’ ability to improvise on the spot and make many unconventional throws look very easy. Mahomes said success comes from the work he puts in in the weight room.

“I use those hips and that oblique muscle to really rotate through that,” Mahomes said before bringing up what some fans called his “dad body.” ‘The people who saw the dad bid have a reason for it: those are the obliques. I understand them well.’

That line made Brady chuckle as he said, “We’ve got to keep a little bit of padding in there. We’re getting hit all the time.”

Here’s the full interview:

Brady will be on hand for the Chiefs-49ers showdown, which begins at 4:25 PM ET on FOX.
