There's only been 3 teams with 8-8 records or worse that have won divisions since they changed to the four division format 12 years ago. In the same time there have been just six teams that have had 12 wins as a WC. That means that if the 48 games played in that time, at most three fit your scenario. There were ten total teams with 9-7 records or worse, so we're thinking there were at most six games that had a three game W-L difference.
That means the great majority were at worst a 2 game differential, which doesn't really bother me.
The way I see it, is 95% of the time, it will play out exactly like it has, 4 division winners getting home games, but the unusual situation like this year where a 12-4 team is stuck as a 5 seed won't happen. We also won't get that random Seattle 8-8 nonsense from 2 years ago again.
Most of the time, stuff will go down exactly has it has, but on the rare occasion like this year, the right team gets to have the home game. I mean theoretically, you could have a 15-1 5 seed, sending them on the roads in the playoffs would just be unfair.
