Maybe, but that's another thing about the tourney: It's not about the best teams. Iowa...hell, Rutgers...would dominate Rhode Island and VCU--just to mention two of many--seven days a week. Sure, it's cool that teams like that are included, but not so cool when they nudge your team out.
BTW: RPI is, and always has been, BS. You really think Rhode Island is 40 spots better than Iowa because the RPI says so? And because the RPI is so awful, the committee is finally ditching it next year--about 20 years later than it should have happened.
