They also kept WVU at a #2 despite their loss to Oklahoma State. I think that this is a recognition of the strength of those losses (imagine that, getting the same treatment that the SEC gets in football). Four Big Ten teams among the top 8. Hope that believed strength proves to be accurate.
Does not hurt that Villinova and Florida State lost yesterday. Seems like any team that could displace the Buckeyes ends up losing as well. Little surprised Houston has not moved into a #2 seed but they just are not getting much credit for playing American Conference competition.
