We gotta realize that the NFL is literally MAGA Country in terms of a sports league. The league being majority Black, I doubt the players, for the most part, are Trumpers, but the owners, a lot of coaches, and front office personnel around the league are probably MAGA supporters on the low; some might be open.
I'm willing to bet a majority of football fans, politically speaking, are Conservative/MAGA leaning; unlike the NBA, the NFL fanbase is very conservative, filled with middle-aged White boomers and Gen X types.
I wouldn't be surprised if the Eagles owners or a fraction of their front office forced the players to attend this potential White House gathering.
