This Kentucky team is easily the class of college basketball. They will dominate this year. Duke and Wisconsin (because they are capable of hitting a bunch of 3's from all 5 positions and not dependent on driving into Kentucky's shot blockers) are the only teams I see as having a chance to steal a game from the Wildcats.
But no way are they one of the best teams ever. College basketball is very watered down. Think of how one of the Alcindor lead UCLA teams or even the Worthy-Jordan-Perkins UNC team would fare...UNLV or Duke of the early 90's...the '96 Kentucky team...even the recent Florida squads led by Noah-Horford-Brewer. This Kentucky team would struggle to beat the best of the best.
They have great depth, a bevy of McD's AA, and will be a heavy favorite to win the whole thing. But while they have a good number of future NBA players, not one of them is a transcendent star. They don't have a Jordan, Durant, Anthony Davis or even a John Wall or Demarcus Cousins among them. They're a deep collection of talent benefitting from a mediocre era of college basketball, not an all time great.
