Wow. I cannot believe that Rutgers was left out of the tournament! I really feel sorry for them; they worked so hard and did so well.
Yeah, doesn't make much sense to me. Rutgers went 44-15 this season. They finished 2nd in the Big Ten. And their RPI was also second best in the Big Ten at 42 (there were teams below 42 that received tournament invites, yes RPI isn't everything).
While the committee isn't supposed to pick teams based on conference affiliation (they are supposed to examine each team independently), it almost seems like Michigan stealing a bid forced Rutgers to the sidelines. Rutgers was definitely better than Michigan for the season as a whole.
The Big Ten really has never had much respect in baseball. Not sure if they deserve more, but when the conference RPI ranks the Big Ten as 8th, it's hard to expect much more love.
