Are you going to win the PAC 12 North by being "just enough?" Cause that's what that sounds like to me.
Welp, I guess I asked my self if a 16/17/18 year old kid could eye-ball the number of seats in a stadium simply by standing in the middle of the field, and I determined they probably can't without help/prior knowledge.
So, in an effort to appease your argument, I figured "big" stadiums have more to do with the structure/architecture of the stadium and LESS to do with the number of seats. I believe you can make a 45K seat stadium look big as hell by building vertically. Our south side press box looks HUGE, why though? Mainly because of three things: 1st: The press box rests on top of a hill, while the rest of the stadium sits "below" it. 2nd: Our north/west/east grandstands are not very large or "deep". 3rd: The rest of the buildings on campus near the stadium are not very large, visual comparisons are skewed.
I believe WSU can make a VERY IMPRESSIVE (read: "not just enough") huge looking stadium and recruits will have no idea the official seat count is "only" 45K.
Plus, you didn't answer my question, if a 45K seat stadium can accommodate 51K fans (comfortably), how big is that stadium really?
