Rutgers and Maryland were great adds, I agree they had a lot going for them. But you are under-rating Connecticut which does similarly in many metrics. Almost 20 million people live within a 2 hour drive of Rentschler field; and apart from BC and UMass which have few fans there are no other FBS programs in the region. Once you realize that state boundaries are not as meaningful in the northeast as they are in the rest of the country -- UConn by the way has a regional preference program which offers reduced tuition to New England and New York students -- then maybe UConn's strong brand presence in Boston and NYC will be more understandable to you.
Football is a relatively new sport in Connecticut but it is growing fast. Connecticut is now producing 10 BCS level scholarship players a year, 16-20 FBS level, and the number grows almost every year. High school football is becoming more competitive. The move of UConn football to 1-A has greatly increased investment in football and Connecticut high school coaches are benefiting from clinics by UConn coaches.
Texas and Florida are tremendous football states, yes. But you also have to look at the competitive environment. With the influx of money into college athletics, many schools are upgrading. In Texas, TCU is now a BCS school, Houston and SMU want to be, Baylor and Texas Tech have made big investments in football, North Texas and other small state schools have moved to FBS, Texas A&M moved to the SEC, at every level the competition is increasing and the market is getting divided into smaller slices. Similarly in Florida -- USF and UCF are moving up and making big investments and could become B12 schools. So we are looking at 5 BCS schools sharing a state with 19 million people -- one that produces a lot of football talent, yes, but that every school in the country recruits. That's 4 million people per school -- the size of Connecticut, but without UConn's out-of-state reach into major population centers.
Based on football metrics, FSU is way ahead of UConn. But now that conferences are forming their own networks which need year-round inventory, and with poaching of the NCAA basketball tournament the next potential way for major conferences to increase revenue, basketball is becoming as important as football from both a branding and revenue perspective. Basketball has always been central to ESPN; it is becoming so the BTN and SEC network and Pac network. Also, markets become extremely important as they become opportunities for national brands like Michigan, Ohio State, Alabama, etc, to broaden their fan base into extended geographic regions. Visiting New England regularly, and appearing on New England cable TV, picks up many fans for Michigan. Markets are extremely important to the new conference networks. The B1G now has to start thinking like ESPN, and emphasizing basketball for the same reasons ESPN has always done so.
You mention AAU status and I agree that UConn must join the AAU before the B1G will extend an invite, unless UConn has been offered by another conference and the B1G is forced to decide. But it will happen. I don't know the timetable but the investments already funded will make UConn an AAU school within 5 years. It may happen quicker if UConn develops friendships in the AAU.
You do know that Virginia Tech is in Blacksburg, 270 miles from Washington DC and in close proximity to West Virginia, Tennessee, and Kentucky? How does it help B1G schools develop relationships with alumni in DC to play at a school a 5 hour drive away? Va Tech makes sense only as a stepping stone to the populous North Carolina - South Carolina corridor linking Raleigh-Durham-Greensboro-Winston-Salem-Charlotte-Spartanburg-Greensville; but then you need to poach the heart of the ACC, in which case UVa would be available. Va Tech is nowhere near the prize that UConn is. West Virginia might bring more than Va Tech.
You mention overconfidence. No one is overconfident. UConn has its warts and has to address them. They are working on it. The state under-invested in the university for a long time, thus the university's stature has lagged what its market supports. But now that the investments are being made, there will be a reversion over time to the level the market supports. That will raise up UConn and pull down schools like FSU and Texas which are facing growing competition.
