I really don't have any problem with what the OP wrote. If you feel you've gotten in a bad investment but have a way to get out of it if that is the right decision for you than who are we to be so critical of that and insinuate that the OP isn't a "true fan"? Should true fans be a bunch of lemmings that follow a program off the cliff?
Hell, I'm feeling a bit ripped off by my purchase of ESPN's Full Court package, bought pretty much so I could follow my 'Clones all the way from Colorado. I DVR'ed last night's game (picked up a shift at work for a friend), but after seeing the final score and reading the recap online, I'm not going to watch it.
Sounds like I'm around the same age as the OP and that we have a similar background when it comes to ISU BB fandom. I was more or less raised on going to ISU basketball games in Hilton as a kid. I remember coming back from 18 down against Oklahoma State because I was THERE. But with the disappointment this season has brought to me so far, it just doesn't matter as much as it used to.
I would love to see McDermott succeed (I know, everyone would). I think he's a man of terrific and impeccable character, and it's sad to see to see him struggle and deal with a bunch of bad breaks (which I hope objectively everyone can agree with) while arrogant jackasses like Lane Kiffin keep on falling upwards for no good reason. But.....for whatever reason, it's just not working. I don't like making coaching changes either, Iowa State has done that too much since the mid-'90's (average length of tenure for ISU BB coaches post-Orr, not including McDermott, four years). But at the same time, we should not continue to keep on digging ourselves a deeper and deeper hole.
Maybe it's not as tough for me as it for others. I also have allegiances to UNI (got my undergrad degree there) and Central Michigan University (got my masters there). UNI having such a great season in basketball so far helps alleviate the disappointment of ISU for me. Same for both ISU and CMU having great football seasons while UNI was a disappointment. I was cheering for ISU over UNI in basketball, as I thought that an ISU win would be more important for the Cyclones than a UNI loss would be for the Panthers (sadly, right now that win can't really be considered a good win for UNI anymore).
I guess my point is I agree with the OP. If I was in his shoes I would likely be making the same choice, as painful as it would be.
