When determining playoff structure, it's a balancing act between entertainment and giving the best teams the best chance to prove it. Having the World Series determined by one game would be really exciting but... What is supposed to be proven that wasn't in a 162 games schedule? We already know who the best teams are. There is nothing a seven game series outcome can provide to show those 162 games didn't get it right except being able to win specific games in specific circumstances. Be it a one game do or die or a five or seven game series the test of the playoffs is different than the regular season in that respect. It takes all the teams with an argument that they are the best, weights it for the ones who have the best argument as dictated by the regular season, then puts them all through a specific set of tests. The new format creates an extra circumstance that the lesser of the playoff teams have to prove themselves in. Which given their failure to succeed in the regular season to accomplish their goal seems fair.
