He didn't say one-and-done players, he said one-and-done talent. All of those teams had players with the talent to be one-and-done.
Okay, even so, lets look at that.
So did Oklahoma State with Lebryan Nash (even though he chose to stay).
So did Texas with Myck Kabongo (even though he chose to stay).
So did UCONN with Andre Drummond.
So did Indiana with Cody Zeller (even though he chose to stay).
Florida had one and done talent with Brad Beal.
Duke had one and done talent with Austin Rivers.
Memphis had one and done talent with Adonis Thomas.
NC State had one and done talent in CJ Leslie.
Baylor had one and done talent with Quincy Miller.
Obviously Kentucky had one and done talent.
And as you said above, those teams technically had players who COULD have been one and done (UNC, Ohio State, Kansas, Syracuse, etc.)
I hardly see how all the one and done talent is focused on 5-6 teams.
I just listed at least 15 teams that has "one and done talent".
And either way, there's still a great blend.
Teams like Michigan State, Georgetown, Marquette, Michigan, and Louisville are just some quick examples of teams that almost NEVER get ANY one and done talent. They just build their players are compete with very experienced upper-classmen.
They've all had great success in recent years.
Again, one and done players, or one and done talent, are not bringing down college basketball.
