Forget Kylie ... Sean Payton is the best influencer on social media.
... this according to PFT Commenter, who tells TMZ Sports the Saints head coach's TV appearance in a Barstool Sports "Roger Goodell Clown" shirt has caused sales to skyrocket!
EVERYONE was talking about Payton's shirt on Wednesday -- when the Saints coach went on camera to talk about the blown non-P.I. call in the NFC title game that cost N.O. the game.
You can see Payton rocked the shirt underneath his pullover -- an obvious shot at Goodell -- and the crew at Barstool LOVED the publicity.
"Doesn't surprise me at all," PFT Commenter told TMZ Sports out in Atlanta ... "Sean Payton's a badass."
PFT says sales of that shirt are WAY up -- and he's considering customizing a new anti-Goodell shirt in Saints colors for all of the people in Who Dat Nation looking to send a message to the Commish.
There's more ... PFT also talks about his run-in with the police and the FBI after using a fake media pass to sneak into an NFL Super Bowl event this week ... and why he's on thin ice in Atlanta.
