The problem is, the league doesn't want to dilute the importance of the divisions.
I don't know how it works in hockey, but even in basketball, the top 3 seeds in each conference are the division winners.
I suppose that maybe it is not as big a problem in the NBA because there are 6 divisions instead of 8 and more teams have the opportunity to make the playoffs.

Unless the NFL restructures the divisions and cuts out a few, I don't think there is anything they can do about this.
