How about the all time undeappeciated team? 87-88 team had Jon Smith, Ala Abdelnaby, Biily King, Greg Koubek, Kevin Strickland, Phil Henderson, Quin Snyder, Robert Brickey all contributing at a significant level. Brickey and Strickland were studs. Even Danny Ferry was and continues to be underappreciated eben though he was player of the year the mect year. This team beat UNC at the Smith center-2nd time in 22 years- and went to the Final Four.
Ferry was ACC POY in 1988 and 1989.
I would nominate the 1987 team. Duke had lost Dawkins, Alarie, (D) Henderson and Bilas from the 1986 team. Folks were predicting that Duke would have trouble making the NIT. Duke was unranked in the pre-season AP poll and was picked sixth in the ACC.
Tommy Amaker was the lone returning starter. He upped his scoring, while becoming national defensive player of the year. Ferry led Duke in scoring, rebounding and assists. But it was a group of 1986 reserves-Kevin Strickland, Billy King, John Smith, Quin Snyder--who elevated their games. Senior Marty Nessley and freshman Robert Brickey added depth.
Duke went 24-9, third in the ACC, losing a competitive game in the Sweet Sixteen to eventual champions Indiana.
Prior to that season, the narrative was that Mike Krzyzewski had built one great team. After that, the narrative was that Mike Krzyzewski had built a great program.
