I don't see any reason for posters to attack Oldfan, who is a longtime fan and supporter of the program.
Those without short-term memory loss can probably appreciate where he is coming from. The University (and folks like Oldfan) view the "success" of the basketball program as something more than just wins and losses. They want to win, but they also want the program to be run and to be populated with citizens that are a credit to the school. Some may think that is an antiquated view, but it's certainly understandable. For those people, the end of the Jarvis era was an embarrassment on many levels. As a result, they were willing to sacrifice more immediate on-court success (or the possibility, anyway) in favor of bringing in someone who was an upstanding citizen who they thought would build the program over time. I'd hazard a guess that some of them are still a little miffed that Norm didn't get a chance to coach his seniors.
Obviously there are lots of folks here who don't agree with any of that, and for whom the only relevant question is whether we are winning games. That's your right, just as it is Oldfan's right to have a different opinion. There's no reason to attack anyone for that kind of philosophical difference.
Having said all that, Norm was a mediocre coach who tended to make the least of the talent he recruited, especially on the offensive end of the floor. I personally found it hard to judge the talent sometimes because of what he did to them. Who knows what Justin Burrell, Larry Wright, DJ Kennedy, and others would have done with a better coach? (Note that I have omitted Sean Evans just to annoy Bobre). He finally started winning some games towards the end of his tenure because he had a group of players who had been together for long enough to find roles and develop some chemistry. Picking up Dwight Hardy helped too, though he managed to misuse him and make the least of his ability (par for the Norm course).
Lavin has clearly recruited better talent. It remains to be seen what he does with it. If Oldfan is suggesting that Norm might be a better coach (not recruiter) than Lavin, or perhaps that their coaching ability is comparable, then I don't think that's off-the-wall crazy. Norm's teams certainly played much better defense than Lavin's teams have, and probably presented more options on the offensive end.
It's worth noting that Lavin's best team thus far was the one with Norm's players, especially Hardy, who was a Norm recruit.
Lavin is a much better recruiter and will ultimately win a lot more games based on talent alone (though again to Oldfan's point, Lavin started in a much better place than Norm did, and he started there because of Norm). By the end of this season we should know whether he's a better coach. I certainly hope so.
I don't believe anyone attacked Oldfan, just the position he asserted.
And I don't accept certain premises that your post relies on. First, I don't think bringing some order and responsibility to the program following Jarvis's departure had to be at the expense of trying to win in the short-term. They aren't mutually exclusive goals. Plenty of people are good at their job and are also upstanding citizens.
Which leads me to my second point, I think yourself and Oldfan are essentially giving Norm credit for not being a disgrace to the University. In what other context would that be appropriate? Do Patterson and Cuomo get credit for not purchasing the services of a prostitute? No, of course not. It's expected that your Governor won't break the law. Does the next University President get a commendation if they don't misappropriate university funds? They shouldn't.
I don't disagree that Norm was a good man, I never had the opportunity to meet him, but I'm willing to take your word for it. And, from all evidence it appears as if he kept the program respectable in the school and broader community. Which is a good thing, for sure. And I would even admit that the aforementioned is part of the basketball coach's job description.
But I don't think that he deserves credit for not being as awful as his predecessors.
