Hopefully I don't get panned real bad when everybody reads what I have to say.
First of all a football program at Mason would definately be a plus. But it probably won't be until another five years before the school gets serious and perhaps build a stadium of some sort.
Here's some things to keep in mind. A bad/losing football program is usually more costly than a bad/losing basketball program. Football fields/stadiums make no revenue once the season is over. Basketball arenas before, during, and after basketball season continue to make revenue off of concerts, and other stage performances (like when Ringling Bros. and Barnum and Bailey comes to Mason every March-May and make parking lot A smell like elephant and horse poop).
Maintenance costs for basketball arenas cost less than football fields/stadiums. It takes much longer to create a sucessful football program than basketball. For a football program to become successful you need to start out as a non DIV. I program and work your way up to a FBS program. Then go from FBS to BCS program. This can take many decades and many seasons of losing seasons and no money being made/loss. Then you got to make it to the BCS national championship bowl game or one of the major bowl games like the Rose Bowl, Sugar Bowl, Orange Bowl, etc.
In basketball you don't need to win the whole NCAA tournament to make headlines and gain brand recognition of your school. All you need to do is make the NCAA as often as you can, and make it to at least the Sweet 16 or Elite 8. Look at FGCU or Davidson. Both did not make Final 4. But FGCU in particular got tons of more students to come to thier school and got several new buildings just by making it to Sweet 16.
Brad Edwards is a good hire, but I think the school needs to get the basketball program back into shape again before even thinking about football. Very few schools that have both a football and basketball program have both of them doing real well. Usually one suffers and other is sucessful or semi decent at best. Another thing to think about.
