Does Jerry Jones have power to bench Cowboys who 'disrespect’ flag? What the law, NFL policy say

Jori Epstein and Chad Baurch bring up some interesting points. I may tune in to my first NFL game to see if Mr. Jones is a man of his word, at least for the first few minutes then it's change the channel to something else. Mr. Baurch tells us that State Collages and Universities and public High Schools that they are part of the Government and therefore would be unable to discipline players who choose to take a knee during the National Anthem. I'd like to get some feedback on a simple scenario. The coach puts in his starters as listed for the first play than grad dully replace all players who have taken a knee with the second or third string. Couldn't that be considered a coaching decision? He or she could easily say that he was not satisfied with the individual players performance.
