Duke's OOC RPI, according to D1Baseball was #1 with a #10 SOS. For comparison, Louisville's was #126 and #210. Tech's was #129 and #137. Duke's only losses were to ECU (0-2, potential top 8 seed) and Coastal Carolina (2-1). 2-0 vs Liberty, who's 37-12. Beat Campbell, who's 33-14. Beat Wofford, who's 35-19. Beat UNC Greensboro, who's only 27-25 but still top 100 RPI. The only losing OOC team Duke played was William & Mary, if I'm not mistaken. Davidson was close at 24-24. Compare that to Louisville, who lost to Cincinnati (29-24, #71 RPI), Morehead State (24-21, #124 RPI), went 2-1 vs Western Illinois (11-29, #261 RPI), went 1-1 vs Eastern Kentucky (21-32, #200 RPI), and swept Bellarmine 3-0 (13-36, #271 RPI). Granted they did beat Vandy and split with Kentucky, but the OOC teams Duke played were overall much higher quality than Louisville. And they had a better record in those games.
