What is the rationale for a state to give up it's spot at Nationals? I can't imagine why the OK state champs would not want to go, unless it's a funding problem or something similar.
Well, there are VERY few teams in OK. I suspect that none of them take SO very seriously. In the past OK has sent teams to nationals and both times they placed 59th. A trip to nationals is quite expensive, there is no doubt, but it also takes a ton of planning on the part of the coach and/or the team captains. I suspect that based on their repeated disappointing performance at nationals, the OK teams have concluded that it simply isn't worth it to put in all of the time and effort required to make it to nationals only to find that as a team, they are not as prepared as they would like to be.
OK has dropped out every year for the past three years and has not attended nationals for the past four years. If I were the second place Washington team (although they don't yet know who they are) I would prepare and anticipate getting the spot to go to nationals.
When it comes to the future, there are three kinds of people: those who let it happen, those who make it happen, and those who wonder what happened.
