I believe Duke did miss out on the NCAA tmt just 2 years ago.
PSU might be a more reasonable foe for Duke.
UMd scrimmages with Duke on 1/20. It wouldn't be any huge surprise to see Duke and UMd start to play again sometime in the next 5 years.
Big Ten vs ACC
Maryland (3) - Syracuse, ND, UVa; Hopkins(3) - UNC, Syracuse, UVa
OSU(2) - UVa, ND; Michigan(2) - UVa, ND;
PSU(0); Rutgers(0)
UNC has noticeably reduced their Big Ten schedule recently, dropping UMd a few years back and dropping OSU this year.
