Three weeks in, and there are just six undefeated teams out of 32. And of those six, who would have thought Buffalo, Denver, Tennessee and Baltimore would be among them.

OK, the Ravens might not count because of their unexpected bye. And I won’t get into Denver’s fortune that Ed Hochuli blew that call last week. Nevertheless, this is turning out to be a wild season. If it keeps up, December, when teams are vying for the playoffs, will be dizzying.
