At 72 years old, Coach K needs to think about hanging it up. He's gone all in on the "one and done" thing for a while now. He doesn't out-coach opponents anymore, he just out-recruits them.
And while the "one and done" players aren't completely going away, the best of them are going to be heading to the NBA. So, no more Kyrie Irvings or Zion Williamsons in Durham.
2015 title notwithstanding, Coach K might've been better served if he had stuck to what had been successful for him, instead of trying to be John Calipari.
