Umm, yes? You cited the 2014 natty. Louisville's defense against us that year was pretty damn good.
76-64; we shot 35%, they shot 48%
81-48, we shot 29%, they shot 45%
71-61; we shot 44%, they shot 41%
In the three games, they totally stifled us twice and the great defensive team that we were, was more or less a non-factor.
I know it's easy to beat on Pitino for his indiscretions, but he's a hall of famer who has taken three different schools to final fours, has won two championships (could have been more if he stayed at UK), and is generally regarded as one of the best coaches ever. You're really thinking that KO has the upper hand on him in any category at this juncture?
I think KO can absolutely coach defense; but saying that KO has "demonstrated that he can do it better" is pretty much disregarding Pitino's 25+ years of consistent excellence.
