I think it's pretty clear that Wisconsin canceled based on a couple different things.
a) Not sure who all is infected and so they shut things down to hopefully shorten the time they have to be shut down.
and
b) The decision was made really easy when they thought that if they play us with their 4th string QB and lose, it hurts their chances of winning the division. If they cancel the game, it doesn't hurt them at all.
That's not being scared of us. It's doing something that, in the long run, helps them to possibly win the division. I don't like it. I think it's a pathetic reason to cancel a game and punish players, coaches and fans that have nothing to do with the getting infected. But, it is what it is.
