The NFL's current policy says as much: that players "should" stand; it is not mandatory.
"I don't think guys are gonna like it", McCoy said on Adam Schefter's Know Them From Adam podcast via ESPN.com, when asked about the possible reaction from players if they are forced to stand for the anthem.
President Donald Trump called for changes to United States tax law affecting the National Football League, fuelling a feud with the league and its players over protests that he says disrespect the nation. Hadn't Donald Trump badly overplayed his hand?
Although the commissioner did not specify if the league will make it mandatory for players to stand during the national anthem, as now it only recommends them to do so, he mentioned that the issue will be discussed at a meeting next week.
Goodell did not specifically outline whether the National Football League will enforce standing during the Anthem, but strongly recommended players do so.
The league countered Trump's tweet Wednesday, calling his remarks incorrect.
"The NFL is doing the hard work of trying to move from protest to progress, working to bring people together", the league said.
"Building on many discussions with clubs and players, we have worked to develop a plan that we will review with you at next week's League meeting".
First, Trump issued a "big salute" to Dallas Cowboys owner Jerry Jones for saying he'd bench anybody who did not stand, before questioning the NFL's special tax status, saying this should be revoked if players continued "disrespecting our Anthem, Flag and Country". Commissioner Roger Goodell has written to team owners saying players "should" stand.
What Vice President Mike Pence's NFL-game stunt last weekend revealed about radical Republicans is their twisted perception of what constitutes a crisis and requires action from our leaders.
