SP+ attempts to correct for strength of schedule. Duke has played "weak" ACC foes Clemson (26th ranked offense held to 7 points) and Notre Dame (16th ranked offense held to 21). We'll see how they hold up against FSU, Miami, and Louisville, but I bet they don't give up half a hundy to any of them.
Duke plays a lot of weak teams in non conference games. And the ACC is no where as strong as the PAC-12.
