If you thought Dufnering was meant only to show a Jason Dufner-like disinterest in what's happening around you, Keegan Bradley proved you wrong on Sunday.
In the final round of the Tour Championship in Atlanta, Bradley and Dufner -- good friends since their 2011 PGA Championship playoff showdown -- were playing together. On the par-4 seventh hole at East Lake, Keegan Bradley holed out for eagle, then in celebration, Keegan Bradley was seen Dufnering in the fairway.
Bradley closed with 3-under 67 at East Lake to finish in a tie for 12th place and in 16th position in the FedEx Cup final standings.
Keegan Bradley is the man really to laud for the massive growth of Dufnering, which he made into a social media firestorm by mimicking Jason Dufner's viral pose in a Dallas appearance earlier this season. It set off a litany of copycats, making Dufnering into a phenomenon.
