I never really recall losing to one. But way back when, both my son and I recruited one in different worlds, I was in d2 at the time, their senior season, both won NT's. IQ does not seem to play as large of role today as it did then, hence, I think they are slightly less effective, even the hybrid versions one could run today.
sims should not be allowed to have superclasses either, for diff reasons though, most human coaches don't want to take on 9 or 10 man soph classes, which keeps them from rebuilding for almost 3 seasons. then, when they finally can recruit, they have to take on walkons, and then almost are forced to have a real unbalanced team for pretty long.
