If I were a top recruit in 2014 I'd be pumped to come to UConn. After I saw the lack of development of some of the players who did go there, I'd probably be less excited. He may have worked just as hard after, but his reputation sank.
I'm sure there are ways in which KO was less energetic than he could have been. But I take the easier path. Less kids wanted to come because it was clear he didn't develop them that well and also he was on the hot-seat. When you have the first losing season in 30 years--three years after a title!--it's not a good look. Now that year had a ton of injuries, but still, everyone saw the ship was sinking, and few wanted to come aboard. We're lucky we still have Adams/Gilbert/CV/Wilson as good blocks to go with some players who might yet develop.
