This might get marketed as a pro-football move, but it's really just an admission that the basketball program has no remaining value. I know there's some optimism there now with Frank Martin, but the A-10 is a shell of its former self and they must know it's only going to get worse as the power leagues gain more power.
This seems like one last Hail Mary to get the football engine going, with the intent to drop or downgrade the program if and when it doesn't work. They can always go back to the A-10.
