I agree he'll have to tweak it & try to keep around some 4-year players for leadership, which out of the points you made, I think will be enough. The question is, what 4-year player will want to be recruited to UK when they know that a one-and-done might be recruited in any year to take their place for that year? Perhaps Calipari decides to take the PG position, as a natural leadership position, & recruit 4-year players there. Will the one-and-done players respect the leadership of that PG? This is all a rather slippery slope & it will take some fine tuning to get it right.
