@drgnslayr I'm starting to wonder if Self is really on the OAD merry-go-round or not. Sure we have had Henry, Selby, Wiggins, Joel, Cliff, Kelly and Ben (kinda). But remember Joel was supposed to be a project. Bill Self said he was the number one pick in year 2 not one. Selby wasn't ready and should have stayed. The same could be argued for Henry but isn't a sure thing. Henry, Wiggins, and Ben are really the only true OAD's we have had and we technically had Ben for two years.
I believe Cliff would have (or at least should have) stayed if there were not eligibility issues. I'm not exactly sure Kelly was ready for the league either but I guess we could lump him in with Wiggins.
I think Self's strategy, whether he chose it or not, has become to get the top talent he can (shoe embargo etc.) and try to get them to stay for multiple seasons. Rush, Chalmers and Wright were all top 15 recruits who could have been considered OAD possibilities since they had NBA size. Arthur was on the fringe at 16 but some thought he could go. Selden was 12.
Diallo is the rawest OAD we have ever seen! Perhaps Self is trying to game the system. Pretend like he wants all of these OAD's but then show them they need another year. Convince a few to stay one or two years and you have a LOADED team! It's working almost as much as it isn't.
By my count, and this could be off, we have had 10 or so top 20 recruits that could be thought of as possible OAD's. Of those 10, 5 actually left after 1 year and 5 stayed 2 or more. The anomalies are Ben and Joel who were ranked in the 30s but soared up the draft boards in their one year playing for KU. Just for context, other 20-40 recruits include: Perry, Frankamp, Greene, the Twins, and maybe a few more that I missed.
