One of the main reasons that the Boise St. Broncos decided to leave the Mountain West and head to the Big East was due to the expected significant increase in revenue for being in a better league.
The reason for the drop is due to the Big East losing TCU, West Virginia, Pitt and Syracuse; then there is Louisville and Connecticut who are openly wanting to leave the Big East. Plus, the league as a whole is on unstable ground regarding their future.
The $3 million per year that Boise State could possibly receive is just over $1 million from what they currently earn from the Mountain West. Add in a handful of East Coast trips and that extra boost in revenue may not be worth changing leagues. That is of course assuming the Big East is paid on the low end of the scale.
It is starting to look like the move to the Big East for Boise State may not be as financial rewarding as they initially thought.
