I don't like the extra playoff team. Not that it matters, it is going to happen.
As far as the extra game, it has its pros and cons. Obvious con is the quality of the first two games is going to be as bad the first games of the season usually are.
It would be cool if they matched up teams in their place finish in the respective conferences to play each other. eg: Chiefs guaranteed to play 49ers next season, unless they are already scheduled in which case the Chiefs would play the team the team with the second best placement not on their schedule, ie: Packers.
