Krzyzewski becomes the eighth coach in NCAA history to post 700 wins at one school and is the second-fastest to reach the milestone. Adolph Rupp holds the standard, having reached 700 wins at Kentucky in 836 games, and Krzyzewski is second with 898 at Duke. Krzyzewski's all-time coaching ledger is now 773-257.

Georgia Tech cut the lead to five at 61-56 with 5:53 remaining on Morrow's three-point basket, but Duke held off the rally by sinking eight-of-12 foul shots over the final 4:34.
