Not really loving this idea much at first glance. It only waters down calibre of teams that get into the playoffs, even if is just one team per conference.
Also seeing that they are going to add a 17th regular season game, cut down on preseason games, reduce training camp practices, and reduce regular season practices. These ideas are bad for the players. Reducing practices even more will only diminish the quality of play on the field, and a 17th game only increases risk of injury for the players.
The NFLPA shouldn't agree to this, but they likely will for less practices, and probably a weaker weed policy. This is dumb on their part. Future me will definitely be pumped for another weekend of regular season football, and two extra games on Wild Card weekend.
