Yes you can, see Kirk Ferentz and Paul Chryst. Not exactly flashy fundraisers. Is it just me, or is the main job of a Coach to win football games and the AD to raise money? I have a feeling if you win more football games than you lose fundraising takes care of itself. But, you know, sure lets fire a guy who won 9 games last year and had a winning record in the Big Ten because he isn't flasy enough, that is a good reason.
