I guess, in fairness, there'd be a LOT of money involved in shifting the games not to mention huge levels of inconveniences to the fans, the networks. sponsors and so many others. It's not very easy to shift the schedule when both teams have already had their Byes, especially at pretty much the last minute. But, at the same time, it's a game that doesn't matter for either team.
It'll certainly be interesting to see how it unfolds tomorrow.
