The link below is to an article that came out last week. Seems like a lot of the smoke is coming from twitter user Bluevodreal, sadly a _ichigan fan/insider. There isn't a whole lot of new info here but instead of the Oklahoma/Kansas/maybe Texas, Big 12-centric rumors that were going around a month or two ago; this article mostly focuses on the ACC. It suggests that a package of FSU/GaTech/UVA/UNC/Duke/ND are all negotiating with the B1G and their timeline for an announcement is this summer.
While I have long been a fan of expansion, at some point, I like OSU playing traditional B1G teams; though I would be fine if we never played Indiana or Purdue in football ever again. This would put us to 20 teams which would likely result in the conference breaking down into four pods of 5 teams that rotate annually or biennially.
