Eh, nature of the beast. Not every championship battle is going to have a "Game 7" moment. I mean Hel, The Seahawks won Super Bowl XLVIII 43-8, but you don't see Roger Goodell going "Okay, for the 2015 Super Bowl, points are going to be resetted at the end of every quarter and at the end of every quarter, both teams will have to eliminate x amount of players til at the 4th quarter, each team only has the best players going all in!"
No, for all the faults that Roger Goodell has for running the NFL, *coughRayRicecough* He at least is smart enough to realize that not every championship battle need to be a Game 7 moment.
