"Are they going to try to punish us all?" the Redskins star running back said. "If not playing football is going to help us save lives and change things, then that's just what it has to be."
Of course, the league's biggest stars appear ready to back Peterson in the kneeling in 2020 ... because, in a video released Thursday night, more than 15 of the NFL's top players demanded the NFL allow them to peacefully protest.
But, the reaction to another round of kneeling protests will not be without controversy ... President Donald Trump just reiterated AGAIN on Friday he does not want to see the protests during anthems.
"There are other things you can protest," POTUS said, "but not our Great American Flag - NO KNEELING!"
Drew Brees had held the same belief earlier this week -- saying he thought the protests disrespected the military -- but when he was hit with tremendous backlash for his comments, he apologized and vowed to be a better supporter of the black community.
