I'd bet Kansas and K-St then go to the Big East as well and they have a East-West split.    I was actually hoping the Big East could survive this, but they need to decide if they want to be a basketball conference or a football conference.  You can't have it both ways.  All the schools you add for football will kill the basketball part, although I guess Kansas and Baylor aren't bad.  The Big East would look something like this.
East: Rutgers, Cincinnati, West Virginia, UConn, Louisville, Temple?
West: Kansas, K-St, TCU, Iowa St, Baylor, South Florida

They'd have to add someone else to get to that magical 12 number for a conference championship game. Temple maybe? Still a very weak looking football conference.  They could try to add Notre Dame but I can't imagine any scenario where Notre Dame would pick the Big East over the Big Ten.  Unfortunately I think the news of Pitt and Syracuse are the nail in the Big East's coffin.

I also hope the Big Ten doesn't take Missouri for granted.  Mizzou was really, really interested in going to to Big Ten before they settled on Nebraska.  Mizzou would be a good addition to the Big Ten but they need to make a decision before Mizzou starts to think the SEC is a better choice..

As far as the ACC goes, if the SEC picks up a few ACC teams like Virginia Tech, Clemson and FSU, and Maryland goes to the Big Ten, you may see basically a Big East/ACC merger.  Duke, UNC, NC State, Georgia Tech, Virgina, Wake Forrest, Miami, Boston College, Pitt, Syracuse, UConn, West Virginia, Cincinnati, Louisville, Rutgers, South Florida.  That would be a very viable conference in both football and basketball.  Though I have no idea where it leaves schools like Kansas, K-St, Baylor, Iowa St and TCU.  They may have to try to survive with smaller schools like BYU, SMU, Houston, Rice, and so on.

All this speculating is kind of fun.

I just hope the Big Ten doesn't sit on their hands too long.  They can sit there and claim they are fine at 12 but the fact is eventually they will going to have to expand.  And eventually is like....now.  The ACC has already gone up to 14 and will probably add UConn and Rutgers to get up to 16.  The Pac-12 is looking like they'll add Oklahoma, OK St, Texas, and Texas Tech to get to 16.  You know the SEC with their football ego will not sit at 14 then.  So while their 3 main rival conferences are going to 16 teams they the Big Ten is gonna sit tight at 12?  No way.  They have be proactive and go out and get teams while there are still teams to get.  Yes Notre Dame makes the most sense but the Big Ten has to ask Notre Dame.  And Missouri is a good fit.  They are an AAU member with above average athletic teams.  They border multiple Big Ten states and fit the mold well.  But Missouri isn't going to just sit and wait patiently for the Big Ten to invite them over while the Big 12 implodes around them.  That's the same thing with UConn and Rutgers.  I can't imagine they are dead set on going to the ACC.  They just want the security of a major conference and the ACC appears to be willing to take more teams.  I'd be willing to guess UConn and Rutgers would listen if the Big Ten came around talking.  But they need to do something before it's too late. And this is what I would do.

Invite Texas.  Somehow incorporate the Longhorn Network into the Big Ten Network and make it some sort of regional channel for Texas.  Let them broadcast whatever they want during the day and then they can broadcast non-conference games and conference games like the Big Ten Network does.  I don't know how the money aspect of it would work, but maybe sweeten the deal a bit since Texas is bringing a bunch of new markets into the fold.  Meanwhile Texas games would now be seen in the likes of Chicago, Detroit, Indy, Minneapolis, Milwaukee, Columbus, Cleveland, and Pittsburgh on the Big Ten Network.

Invite Notre Dame.  It's a match made in heaven and doesn't need much explaining.

Invite Missouri.  I touched on it above but this also makes too much sense not to happen.

Pick another team, probably an ACC school like Maryland.  The exit fee is high but I'm sure something can be worked out.  Maryland is also an AAU member and brings in some nice markets.  If not them, go to BC (I'd actually prefer BC because of the hockey).   They may resist but money talks.  Imagine how big of a tv deal the Big Ten could get with Texas and Notre Dame.  These schools the ACC are getting (Pitt,  Syracuse, UConn and Rutgers) aren't exactly football powerhouses and I imagine Maryland or BC would at least listen, especially if Texas and Notre Dame join.  But the Big Ten has to hurry before Texas runs off to the Pac-12.
