Again, you insist on confusing NCAA Championships with National Championships. Prior to the mid-1960s, the NCAA Championships were not considered National Championships de facto. The NIT was at least as prestigious if not more so prior to then. Purdue was voted National Champion when Wooden played. Of course, Kansas and North Carolina were also voted during that era. They hang banners today commemorating those teams and legitimately so.
You may not like the way things were done then, but that was how it was done AT THAT TIME. Likewise, in football prior to the playoffs, National Championships were voted. Are you also arguing that Penn State, Minnesota, Texas, Oklahoma, USC, Ohio State, Michigan, Army and Notre Dame should not recognize their National Championships because they were voted? That was how it was done then. So be consistent and not a jerk.
