Coach, my wardrobe alone with the age will demonstrate I have been an IU football fan for years...Got hooked as a kid sitting in the Knothole section of the end zone for the cheap tickets close to the field in Btown.
That being said, I was quiet because my expectations were pretty grounded...enjoyed a couple of years during the Corso and Mallory tenures, but pretty darn limited.
Just because one is quiet, doesn't mean they aren't a fan or aren't investing. Simply means they don't fabricate or embellish things to cheer about...they wait until its earned.
Then again, long time Cubs fan....perhaps I have learned to live with limited expectations....and then celebrate when I am surprised.
