This always happens. The league makes all kinds of threats and says a gigantic penalty is coming, then do absolutely nothing when it comes to 31 teams.
Good. That is the right thing to do.(For once) Unless some extreme violations were made by the actual club, knowingly letting infected players in the facility, etc etc, they shouldn’t penalize anyone. If the stories about players practicing on their own are true, well, they have the freedom to choose to get together with buddies & toss the football... you can’t get them in trouble if it wasn’t a coaches plan or okayed by the organization.
