I see your logic and follow your math. I wonder if in this darwinistic scenario if they don't equally weight each round or at least don't weight the first and perhaps second round equally?
That all said, I still am not convinced the breakaway from March Madness paying for D2/D3 athletics will happen - at least not without MAJOR political blow back across all 50 states. Therefore, I think Congress gets involved at least behind the scenes to influence things so D2/D3 athletics don't literally go down the drain because I think that's what would happen. The cultural and economic impacts would be huge - thousands of jobs (coaches, administrators, etc) go away, tourism/travel goes down, alums/donors get pissed and donations go down, etc etc. IF things move in this direction, I think it would be some sort of slow progression and not just a massive overnight knife cut.
The D1 tournament does not pay anything to D2 and D3 schools currently. It hardly pays for D1 schools.
All it pays for is the championship events in those divisions.
The rest of the money goes to D1 tourney teams (about $300m of it), while the bulk of the proceeds fund the enforcement arm of the NCAA itself.
By the way, my math was all wrong, LOL. I based it on the number of tourney teams and it should have been tourney games not counting the Final 4 or the midweek games. So, it should be $8.3m per credit, instead of $15m.
The value of UConn would drop then from $30m per year in credits to $17m + TV value. I would also think that the value of the tourney increasing in each conference's eyes might impact the regular season value of basketball as a whole.
One thing I dd not include here is the value of the women's basketball tournament. As we saw last year, the ratings were huge. I just read an article that envisions a 5-fold increase in the value of the next women's tourney contract; the last one was signed in 2011. They have experienced a 27% year-over-year increase in viewership, and it's now catching up to the men's side.
With the UConn women being even MORE successful than the men, their total tourney credits may indeed result in a few million dollars more for UConn total, taking the school to over $20m+ in yearly tourney credits from men's and women's.
