Far superior opposition? That seems like an exaggeration. Some tough OOC opponents like UConn, DePaul, Ohio St. and Tennessee plus UCLA, who UW played twice in conference. Some really really fluffy creampuffs in their too. Houston Baptist, Mississippi Valley St., SE Louisiana, Kent St., Abilene Christian, Texas St., Winthrop. Wow, that is really tough. Those are some opponents Maryland would approve of. Big 12 vs. Pac 12 conference schedules are about a wash, I'm not gonna give Baylor any credit for tougher competition there.
UW's OOC doesn't contain as many top teams as Baylor's, but they did play Notre Dame and Missouri. Colorado St., Boise St. and BYU aren't chopped liver. Their creampuffs aren't any worse and I'd argue probably not quite as bad as Baylor's. Not seeing this far superior opposition you are claiming.
I went thru and looked at the records of all of UW and Baylor's OOC opponents. Winthrop is quite possibly the WORST team in the country. 1 win in a crappy conference and 2 wins overall. Mississippi Valley St., SE Louisianan and Houston Baptist are all also abysmal. Baylor played more high end teams than UW but they also played more bottom of the barrel teams. Basically your argument comes down to playing 3 more games against good teams in OOC, while ignoring how many truly awful teams they played in OOC. Over a 30 game schedule, that is in no way "far superior competition."
