One of the best hounds I have fed was a 1xGL, GIS. In school he ran over 2 2xers and 2 3xers. As fate would have it he sustained an injury in his first show that lead me to pick him up. Im very confident he would have won that night, but it would have possibly cost me his life.
I have won BIS (in around 1:20) with what turned out to be a 10min cur. I have also had the pleasure of showing a few that put on nearly perfect displays of their craft, but never recieved a trophy. Had they been shown at a large enough event to warrant trophies then they surely would have won them.

So IMO, todays best in show could be tommorows piece of doodoo, but a truely game dog is always going to be game.
