What is the lamest strategy that coaches use off the pitch to give themselves an edge?

My vote goes out to all the coaches out there who have multiple teams of the same race, almost the exact same name, (I, II, III, etc.) and almost the exact same TR. When you challenge these coaches to an even match (according to TS, which is not very reliable but is the best FUMBBL has to offer) they bring over the more powerful team to give themselves an extra edge.

When other coaches do this to me I just play the match anyways, which no doubt encourages them to continue utilizing this strategy. Nonetheless...it's pretty lame. I guess I have to be more careful about specifying EXACTLY which team I challenge in order to counteract this type of powergaming, but in R I'm always just looking to have fun and quick matches, and am not usually looking at all of their teams, just the ones closest in TR/TS.
