Because when rumors are stupid, annoying and ridiculous, you let them flame out. You dont even acknowledge them. This same situation has been hammered the past three offseasons. Though it's got a bit more steam this year, but regardless, it has. When you address rumors, you give a lot of power to the rumor and the people spreading it.
Is any of this making sense? Cuz it sure the heck aint to me.
It is AD Eichorst's policy not to comment on coach's during the season apparently...
