I don't know why, but the jersey retirement discussion really annoys me. For all the good Pollard has done, I think he's dead wrong on this.
I can understand having criteria for retiring a number. I agree that's likely the greatest honor someone can achieve.
Then fine, keep those (outdated) rules but change it to retiring the jersey, or create a ring of honor, or find another public display of an individual.
There is no reason that guys like Tinsely, Fizer, Ejim, Niang, Monte, Haliburton, Purdy, Breece, etc, aren't being honored publicly in some way.
Now to refute Pollard's example of Kansas. I couldn't find criteria directly from the KU AD but found a quote from Bill Self from a few years ago.
First, Kansas doesn't retire a number, they retire a jersey.
Per Bill Self in a 2020 KC Star article, there's no official criteria, but there are "guaranteed" ways to get your jersey retired. This appears to be what Pollard was referring to.
Wikipedia has the list of KU retired jerseys. They've retired 33 jerseys based on this list.
