Making the sweet sixteen with the opponents we faced wasn't great, and it was no reason to rate us highly. I stand by that.
Although I agree with you to a degree, don't forget that there were others with just as easy or easier roads into the Sweet Sixteen:
Kentucky (ETSU, Wake)
Duke (Ark-Pine Bluff, Cal)
WVU (Morgan State, Missouri)
Ohio State (UCSB, Georgia Tech)
Butler (UTEP, Murray State)
Baylor (Sam Houston State, ODU)
Syracuse (Vermont, Gonzaga)
Add Tennessee (SDSU, Ohio) and you have EIGHT of the teams getting there by playing teams whose seeds add up to either 24 or 25. If you rate San Diego State highly, then you can easily make an argument that we had the toughest road of the eight (and can make an argument for us over Kansas State, who played North Texas and BYU). Thus, although our road certainly wasn't as fierce as we expected, it's hard to say that more than about half the teams in the Sweet Sixteen had easier paths. Also, two other teams not listed had only to beat a pair of teams whose seeds add up to 25 to make the Sweet Sixteen. These teams (Kansas, Villanova) failed.
West Virginia, interestingly, made it all the way to the Elite Eight without playing a single-digit seed.
