Agreed. Duke has struggled in the frontcourt against post players like Williams.
If you are looking for a chink in the Duke armor, take a look at Miami’s Reggie Johnson. In the game against Duke, Johnson managed 22 points in 23 minutes of action. For those of you who worship at the tempo-free altar, Miami scored 1.05 points per possession and held Duke to 0.89 per possession when Johnson was on the floor.
It might be a stretch to expect Maryland to win in Durham, but if the line was set at 20, I would take the points.
