With a reduced conference payout Idaho was fourth in the SBC in revenue without subsidies also fourth lowest % of subsidies.
Without looking it up Montana and NDSU should be better than Idaho.
So how does FCS cost Idaho more and not cost the top FCS schools more?
Hell ULM had a budget of ten million dollar a couple years ago.

Coastal will have two temporary bleacher sections next year to get to 15k capacity.
Charlotte has a first class stadium but 15k everyone thought they would rush to expand it they haven't.
NDSU will be at 21k with a newly renovated arena.
Montana is building a nice football operations center 25k and 7500 are their game day capacities.
ODU in CUSA is rebuilding their stadium 22500 .
The P5 pulling away and conference networks HD TVs video game playing children have led to smaller stadiums.
It doesn't do much good to have a big stadium if you average high teens to low twenties like so many G5 do. Add in the tickets sold and it really makes no sense.
Allowing schools to move up without affecting their entire athletic department could be a game changer.
