Wichita probably isn't gettting as much credit as it could because of how people generally perceive the teams it beat:
Pitt - always choke come tourney time, no big surprise they bowed out in the "2nd" round
Gonzaga - didn't deserve to be a #1, only a matter of time before someone showed that
La Salle - a 13 seed who beat a 13, a weak 4, and a 12. Their run was about up.
If the Shockers can take out Ohio St, that's when I think they'll get more press, deservedly so.
