Just going through Wrestlestat in regards to PAC-12. There is 1 per weight at 141, 149, 157, 184, & HWT. The weight class that seems strange to not have at least 2 AQ's is 149. The rest of the weights make sense at only have one based on the quality of conference at the weight.
141 - PAC-12 has 1 guy in top 33 Vasquez ASU at #23
149 - PAC-12 has 3 guys in top 33 Parco ASU #5, Abas Stanford #16, Demas Cal Poly #17
157 - PAC-12 has 1 guy Cardenas Stanford #7
184 - PAC-12 has 2 guys Munoz Oregon St #6, Montalovo ASU #25
HWT - PAC-12 has 2 guys Shultz ASU #6, Tinker Cal Poly #30
