A good podcast from Buckeye Scoop's Tony Gerdeman and Tom Orr:

They mostly agree with the BP sentiments on expansion. The podcast is 40 minutes long, so here are some highlights:
1. It will be nearly impossible to poach teams from the ACC or SEC due to the conference Grant of Rights. SEC expires in 2034, ACC in 2036.
2. However, the ACC has a crap TV deal and schools will likely want to leave. If the ACC implodes over the TV deal, then some schools might be possible Big Ten expansion targets, namely UNC and UVa.
3. Because poaching teams from the SEC or ACC is unlikely, that leaves either Big XII leftovers (bad) or Pac-12 (good). A lot of talk about USC, but they also mentioned (among others) Colorado (big growing market) and Utah (not so big growing market).
4. Kansas is the best of the Big XII leftovers, but their only positive is basketball, which doesn't move the TV needle nearly as much as football. Kansas might be an option if the Big Ten needs a 20th or 24th team in order to form equal divisions (or "pods", to use their term), but they won't be a primary target of the Big Ten.
5. Lack of AAU membership is a deal breaker.
6. Conference expansion will be decided by the university presidents, not by the athletic directors (and not by Kevin Warren).
7. Best options for expansion:
a. Pac-12 schools (and possibly Kansas)
b. UNC and/or UVa (and possibly Kansas)
c. Do nothing and stay at 14 schools

By my count, there are 9 Pac-12 schools that are viable options (meaning AAU members). Here's my order of preference, using a blend of football, academics, and TV markets:
1. USC
2. UCLA
3. Oregon
4. Stanford
5. California
6. Washington
7. Colorado
8. Arizona
9. Utah
