I believe the answer to your question is ... No, we do not know. At least I do not, and I am always looking for recruiting information.
The only “real data” (useful information) are the reports of recruits that actually make official or unofficial visits to OU. If a recruit makes a visit to OU, then we can assume that both OU and that player are at least interested in each other. The visit usually involves an “audition” where the visiting player participates in a pick-up game with the OU team, and also gets to interact with his potential teammates. You can scan this message board and see which players have been here. So far, they have been few and far between.
My guess is that some players make visits to OU and we never here about it. Not every player makes a “tweet” every time they do something.
We occasionally see a report about an OU coach that is watching some player at such-and-such tournament. But these reports don’t mean a thing until the player makes a visit to OU.
Many of us are starved for more OU basketball recruiting information. There is just not a lot out there.
