Me in June:
This is a big challenge for football, because meetings throughout the day break out by position group. As a result, losing 20% of your roster for a month to COVID-19 probably doesn’t mean losing a WR, a TE, two OL, two DL, a LB, and three DBs. It probably means losing 7 OL and 3 DL or something like that, and most teams only carry 7-8 offensive lineman. It’d be virtually impossible to win with 5 offensive lineman off the street, and it’d be franchise malpractice to put a franchise QB out there behind 5 offensive lineman off the street.
I don’t know how they avoid this. It’s going to happen to someone. If I were an NFL GM, I’d have a backup QB in total isolation, working out and practicing with a couple coaches that are also in total isolation. My entire practice squad would be offensive and defensive lineman, and I’d also isolate them from the rest of the team.
I’m surprised it took this long, and surprised they’ve managed to avoid it with offensive/defensive linemen.
