Burgess Owens warned that the National Football League must show some leadership and promote respect for the flag among the young players.
"They need to do something different," the former Oakland Raiders and New York Jets player told "Fox & Friends Weekend." "Young men need to recognize how proud we should be of that flag."
"Our institutions are under attack, God, family, country."
Owens said he has observed that "socialists and Marxists" are teaching black children to be anti-white, anti-family, and anti-American.
President Trump tweeted his outrage about the Giants player who knelt for the anthem on Thanksgiving. The president is willing to tweet and "drive the left nuts," which Owens said he enjoys.
"The NFL needs to step up to the plate, recognize what's going to work for this country. And pride in country, flag, and culture is the bottom line."
If the league does that, it may return to being the great institution we grew up with and were proud to be part of, the former football star remarked.
