There has been speculation on some other threads, some guys are wearing them even if they got the shot, delta precaution. Richardson and Tomlinson are the ones I am wondering about, seen them both wearing them a lot, before and after interviews. PA did an interview with AT and asked, to paraphrase, if it was a divisive issue in the locker room. Once again, to paraphrase, AT responded they were all supporting each other. My best case hope is there are some that are providing sideline camouflage so we can’t know for sure, but that is just my opinion. Neither Cook or Mattison were playing so may have been for the camera
