Jimmy Johnson struggles to grip the 57-pound mahi-mahi he reeled in

At the age of 72, Jimmy Johnson has already accomplished nearly everything possible in the game of football. He won two Super Bowls with the Dallas Cowboys and a national championship at Miami.

Now, he can add catching a 57-pound mahi-mahi to his resume. Johnson reeled one in on Tuesday morning and shared two incredible photos from the catch.

The former head coach still looks like he's in great shape. He must have been to be able to reel in that big fish.

Johnson has become quite the fisherman since retiring in 1999. He shares most of the fish he catches on Twitter, which is awesome. Just two weeks ago, he caught a couple of wahoo.
