I understand the other side of the argument. The more teams you have making the playoffs, the more it takes away from the division winners.
To be fair though, the division winners are not always the best teams in the league. There is something inherently wrong with an 88-win team making the playoffs over a 95-win team simply because they are in a different division.
Also, randomness is such a huge factor in the outcome of baseball games that even after a 162 game schedule, it's very likely that the best teams are not the ones who end up in the postseason.
So I'm okay with the expanded playoffs.
