Fortunately I don't think this scenario is likely to happen with us defied. Being that we are in districts, we have to earn our way into regionals.
In case you haven't seen this already a recent blog post (
http://www.usfirst.org/roboticsprogr...ct-points-2015) said that teams will want to focus on ranking well. I think this will stop even potential un-GP teams from "throwing" matches. The only thing would be if they are picked by an alliance that makes it to finals I suppose.
There are also some other interesting tidbits about rankings in the post. Good luck, we'll see you at Shorewood.
