I think if the talent was equal for all teams, the Rays and Brewers especially would still win more games. Why? Situational hitting. Both the Rays and again especially the Brewers work hard and take pride in their effort and ability to size up the pitches they are seeing, put the bat on the ball, get on base and move runners along. And it doesn't hurt that both teams are very good at managing a pitching staff.
The first 2 games of the WS have been excellent to watch; great baseball.
