Duke has 3 elite players who essentially play the same position and 1 good, but not great point guard. But that's pretty much it. A center who has shown us nothing in 2 years and a bunch of mediocre at best bench players. Big drop off after 3 players.
Kentucky, on the other hand, can go 8-10 deep with little to no drop off. We have 4 big men who can put up 20+ on any given night, 3 point guards who could start for almost any team in the country, and a couple of small forwards/shooting guards in Johnson and Herro who can get a bucket any time they want to.
Probably the best answer.
