Agree. Team A wins toss, gets ball. Team B plays defense, which last time I checked is a huge part of the game, and forces a punt, gets ball and scores. Game over.
To those who say, "what if the team that wins the toss runs back the KO for a TD, it isn't FAIR!" To those I say, Special Teams are part of the game as well. Tackle the freakin' kick returner...or stay in your lanes.
Please, not the college abortion.
As far as a baseball-type approach, still wouldn't buy it. See above.
