Provided that the risk of spreading Covid is gone, I think I'm on board with just having teams play through it with their backups.
I wouldn't want to see an actual safety issue for Derek Carr here though, if that's the concern. I guess with the offensive line, that is a unique issue.
But if it's about a team being able to stay competitive on the field, I'm more inclined to say screw that. Every team has the same risks and protocols. Teams with more depth to withstand injuries/illness will be better off. Teams get ravaged by injuries all the time. If you're looking at it from a competition standpoint, maybe Tampa shouldn't have been forced to play Thursday night against the Bears since they were ravaged at WR. If those guys all had Covid instead of just being unable to perform due to injury, would they have rescheduled the game?
What I don't like is some random, shoot-from-the-hip approach to this, like: "well, the Raiders have a bunch of guys out, so..." or "Patrick Mahomes can't play, so..." Just need to make the call based on the risk of spreading Covid to others and stay consistent about it. Otherwise, you'll have tons of unfair inconsistencies and biases.
