A lot of it comes down to Houston's young starters... If Framber and Luis Garcia pitch with the sort of effectiveness they had at the end of the series against the Sox, they'll be hard to beat... if they look more like they did at the beginning of the ALCS, Braves will have an edge.
This will also be a test for the Braves pitching staff... at the moment, Houston is in a lot better place offensively than Milwaukee and LA were. In order to be the best, they'll have to keep them in check.
There's a lot of apathy around both teams for a variety of reasons, but in terms of on the field talent and match-ups and quality of baseball, it should be a great series.
