Not necessarily. What would people have called the ceiling for 2011 after the fourth straight SEC road game loss? Or 2014 after the South Carolina game?
There are alternative paths that get you to a high ceiling. Here's the most plausible one: Ulis-Murray-Briscoe mesh into a killing machine on both ends of the court, shutting down opposing guards and ripping through opposing defenses. In a one-and-done tournament, if that trio got hot, they could carry you a long way. An ADEQUATE front court anchored by Lee and Poythress playing just to their ability, along with something from Skal, Humphries and Willis would be enough if that happened.
Look at UConn in 2014 with their guards. Was their front court any better than Kentucky's would be with just normal improvement between now and March? Feast on these stats: Nolan, zero points. Daniels, 8 points. Brimah, zero points. Those are the only players who are listed in the box score of the final game as playing forward or center for UConn. Surely Lee, Poythress and SKal can match that.
You could say, well, UConn was a fluke. There are better teams this year. There were supposed to be better teams THAT year, which is why a 7 and 8 seed matched up in the finals. No teams this year are close to unbeatable. No team this year is as good as ANY of the top four last year: UK, Wisconsin, Duke and Notre Dame.
