NFL teams fight for home field advantage all year long in the regular season.
There's a huge uproar from analysts and NFL fans about re-seeding the NFL playoffs so that a just above average divisional winner (the Eagles) don't get home field over a team with a better record (the Saints)...
It looks like Major League Baseball will make a major change for the 2012 playoffs. There is a proposal to add one more Wild Card club for each league.
That's a great idea.
