I dont know if this has been suggested. But why not have the players who have played in the game between the designated quarters shower/sanitize between each quarter and put on fresh jerseys. Think about it you could offset which players sanitize during the end of period so that you offset which players at a certain position is gone and you'd only lose them for a half drive or less (since they'd be gone by end of 1st quarter or before it ends if they're a defensive player and the offense in on the field and vice versa. Then at halftime you could do mass sanitizing and only have to plan for end of third quarter. It would show that your trying to do everything to keep players safe. Just a suggestion, would love to hear what you guys have to think...
