I might be about to tick you off, but here's my take.
Football is a team sport. And while there are individual successes and failures on every play, the celebration of one's individual accomplishment on the field is unnecessary and draws attention to the person rather than the team as a whole. I for one despise these little displays, no matter how cool some can be, and wouldn't mind players being ejected for them. Even the chest bump, which does show solidarity (kinda) is just so overdone, I'm sick of it. When these clowns will even stop to dance or whatever after making a good play when they're hopelessly behind on the scoreboard - and you know that happens a lot - well something should be changed.
I think these attention seekers should do the job they're paid extremely well to do, STFU about politics, and if they want to be a celebrity then do something worthy of all that attention.
