The Indians are very good but, in the MLB thumb on the scales category, no more likely of help than the Astros. The Yankees will get as much help as MLB thinks it can get away with...and then some. Also, the TV coverage will be unbearable. The TV people should be salivating over the thought of two 100-win teams going at it (and again in the Series, potentially), but they won't; they'll want the Yankees all the way and will crack a 4-hour+ boner over a Yankees - Dodgers World Series.
But the Astros will have home field advantage and a better shot at beating the Yankees, MLB's thumb notwithstanding. I honestly can't decide.
