Numerous NFL players agree with Slay's feeling that if a team has a COVID outbreak, they should forfeit.No game in NFL history has ended in a forfeit.Darius Slay@bigplay24slayDamn I thought the team would have to forfeit!!! This crazy🤦🏾‍♂️2:35 AM · Dec 17, 2021122611853Damn I thought the team would have to forfeit!!! This crazy🤦🏾‍♂️Another defensive back, Quandre Diggs, took more of a direct approach. He called the NFL Players Association weak while retweeting a quote from K.J. Wright. Wright claimed that if the Raiders were the team that caused the outbreak, they'd still play tomorrow.Nino@qdiggs6PA weak af! twitter.com/kj_wright34/st…KJ@KJ_WRIGHT34I pay my player dues just to get lied to and the rules bent! @NFL @NFLPA If it was the other way around I swear we would be playing tomorrow3:00 AM · Dec 17, 20211068101I pay my player dues just to get lied to and the rules bent! @NFL @NFLPA If it was the other way around I swear we would be playing tomorrowPA weak af! twitter.com/kj_wright34/st…Speaking of Wright, the Las Vegas Raiders linebacker had more to say. He was upset with the NFL for postponing their game when the plan the NFL laid out before the season involved no postponements.KJ@KJ_WRIGHT34We agreed that their wouldn’t be any postponed game this season right?! twitter.com/_willcompton/s…Will Compton@_willcomptonOn behalf of the boys in Vegas we are ready to play.

Amos' tweet wasn't angry per se, but he questioned what the NFL will do going forward. It's a fair question from Amos, as cases could only increase with the holiday season upon us.Adrian Amos@_SmashAmos31They stressed Get the vaccine to prevent outbreak because “we are not canceling or postponing games” So now is there going to be a particular number that has to be out for a game to be changed or is this a one time thing?

Not angry just curious.Another person who was frustrated was Raiders owner Mark Davis. Davis was outspoken about not wanting his game postponed before the NFL announced it. Davis believes his team is at a competitive disadvantage now.Adam Schefter@AdamSchefterRaiders’ owner Mark Davis told @PGutierrezESPN that moving the game back two days is a “competitive disadvantage to the Raiders.”3:59 AM · Dec 17, 20215567494Raiders’ owner Mark Davis told @PGutierrezESPN that moving the game back two days is a “competitive disadvantage to the Raiders.”Raiders linebacker Will Compton followed his owner's opinion.Will Compton@_willcompton“Any time, any place” - not the Browns3:11 AM · Dec 17, 20217281888“Any time, any place” - not the BrownsCasey Hayward took a direct shot at JC Tretter of the Browns.

McLeod doesn't see why the Eagles' schedule has to change because Washington has a COVID outbreak.Rodney McLeod@Rodney_McLeod4So we have to suffer, and compromise our schedule because of another teams mistake.

Flexibility is how the NFL survived through the 2020 season, and flexibility is being asked of the players again. This time, however, frustrations have begun to boil.
