Pat McAfee's WWE-style promo against famous New York Knicks fans during Game 4 of the Eastern Conference finals isn't sitting well with John Mellencamp ... who seems to be calling out the former Colts punter for his antics -- dubbing it "poor behavior."
The 73-year-old shared ahead of Game 5 between the Pacers and Knicks that he was disappointed "Hoosier hospitality" was not extended to the NY guests at Gainbridge Fieldhouse on Tuesday.
"I was embarrassed when somebody, under whose direction I don't know, called out some of the people who had made the trip from New York to support their team -- and in turn, support our team," Mellencamp wrote on X.
