They should be and a ton of media folks have latched onto this bracket asking the same thing. WSU was and is a great team as I said before look at where UK started in the polls so it isn't like they were chopped liver. Had WSU lost to K-State my opinion may change a little bit.
The same media that you are using to support your question is also the same media that says there are no great teams in college basketball this season. There are many good teams; no great teams.
The pressure that comes with the 1-seed is the same pressure Gonzaga had to go through. Fact is they couldn't sneak up on anyone and the UK team they played had superior talent at each position, worst possible matchup WSU could draw. a mid-major that played nobody in the regular season and whose coach demands they be a number one seed and who says, "wolves are not concerned about the opinion of sheep" . . . . well, when the NCAA puts you in the toughest of bracket so that you actually have to prove you have fangs . . .well, gues what, "the sheep are not concerned about the whining howls of wolves in a trap."
