Johnson was a better defensive player, Curry a better offensive player. I certainly wouldn't say Johnson is clearly superior to Curry. And you overlook the rest of the team as though it suddenly makes Kansas the clearly better team. That's a team that struggled offensively against good teams and loses its only two impact offensive players. I'll gladly take Cook, Thornton, Curry, Sulaimon, Dawkins, Gbinije, and Murphy over Johnson, McLemore, Releford, and the borderline major-conference players they have backing those guys up. And I'll also gladly take Kelly, Hairston, and the Plumlees over Withey, Young, and Ellis.
As with Green at MSU, you're underrating just how important Taylor and Robinson were to everything Kansas did. McLemore isn't as good as Murphy. Ellis is likely to have less immediate impact than Sulaimon. I don't think I'm underrating their recruits/redshirts all that much. They were 3/4 star recruits. If you're going to discount Marshall Plumlee and our 5-star recruits then I'm going to even further discount Kansas' 3/4 star recruits.
