If a coach doesn't "owe" fans anything or any explanation, than that coach (or supporters of the coach) can't gripe and moan when those fans don’t feel the need to fill the seats. It works both ways. Once a coach doesn't feel somewhat accountable to his/her fan base, the fan base in turn owes no loyalty to the coach.
The folks that spout off the "Support your team regardless" argument can't have it both ways.
Basketball is a multifaceted entity. It doesn't serve the needs of only one entity.
1. It's an activity/career for players and coaches,
2. It's a revenue maker for the university
3. It's entertainment for consumers (i.e. fans).
We can have a conversation about the which of these three are the biggest priority but regardless once it no longer becomes entertaining to the masses it no longer becomes a revenue maker for the university and ultimately no reason for a high(er) paid coach.
Ergo If the University of Iowa ever wants to have a basketball program that generates revenue, its coach better darn well do what it takes to appease fans and get them back into the seats. For me that includes answering questions about why his son, a walk-on who by everyone's opinion (including Coach Lickliter) isn't a Big 10 caliber player, saw major playing time during a conference game.
