I think the reason has a lot to do with time. He's been the man in charge for so long, it's natural for people to want to respect it and appear to not come across as envious and jealous. It's the typical high road argument.
The thing is you cannot just allow the guy to play by other sets of rules. Has anyone explained yet how regions were designed by location, except for Duke? Is that just another conspiracy? What happened there? How about all these eligibility cases that strict liability didn't apply? Has it even been explained?
If coach K was as good of an overall coach as Cal was in reality, he would probably have 7 or 8 championships by now with his unearned tournament wins. With the competition being so close in the elite eight on, all it takes is a slight advantage and you get so many odds. You give Calipari all those favors/years and it's over. He's a defensive minded guy so I have no doubt in believe it.
There's been years where Duke shot more free throws at home than any team in America. I remember the Parrish article on it. It was something like 2.5 more free throws per game at home than anyone, and they were somewhat of a three point shooting team lol. I mean, it's no conspiracy.
