Well, the playoff teams all seem to willing to replay their games, and the vote seems to favor a roll back.
As pointed out by billstein, please note I am very reluctant to do this and it will only happen again in extreme circumstances, like what happened here where a whole team got gutted and free agents flood the market. It won't be done, as he suggested for minor mistakes made my careless teams.
Detroit's owner will be booted from the league and someone from the league (me or SF depending on who has time) will temporarily take control of Detroit to figure out what went wrong and stop it from happening.
Good luck to all the playoff teams in the deja vu matchups.
I will reach out to jdavidbakr and keep you updated on the status of repairing the league. It might take some time.
