The bar has been set so high because of K, but two years since 10 losing in the first round, one (16) where they barely made it out of the first weekend, to then lose the next game, and then this past roller coaster season, not getting out of the 1st weekend.
Personally, I think it has taken Coach K some time adapting with the one and done mindset player. I think he didn't have good luck with them meshing with returning guys until Okafor in 14-15, and had Sulaimon stayed, I don't think Duke wins it all that year. Hell he used to kick Laettner out of practice, yet it's in Sports Illustrated when he benched Parker in 13-14 season where his mother texts an assistant coach that she's coming to Durham to talk after her son was on bench during the end of the NC State? game.
The main disagreement that you and I have is the amount of stars to take in. I say 2-3 one and dones, you and some others are fine fielding as many of them as possible. Time will tell, I just am of the opinion give K a team where they all know their roles, and the chance of success is higher. Everyone can't be a chef in K's style, minutes won't allow that. Someone has to wash the dishes
