There are many considerations that need to be weighed when created a playoff format. Fans don't want to think that the best teams don't have a fair opportunity to demonstrate that they are the better team. 9 innings does not provide a very good opportunity. Again, it might be compared to the NFL wildcard game being 12 minutes long. It runs the risk of feeling like a coin flip. Now, if the wildcard play in game actually were played against the 4th and 5th best teams in each league, I wouldn't really care. In the AL, I don't think that anyone could argue that this year, however. Then, it comes down to just being lucky enough to play in an inferior division. Not very satisfying to me. There really is no right or wrong answer here. I have a sneaking suspicion that the one game playoff won't be a long very long, however.
