In 1992, a friend of mine was "unifying" two leagues and needed a couple bodies to fill in the holes. I agreed, as did another rookie friend of ours. I have no doubt we were supposed to be filler so that the two league champs from 1991 would have an easy path to the title unification game. Of course, what actually happened was that us two rooks ran away with the league and met in the final, with me winning. It was an instant rush, magnified because all these people were furious every time they lost to one of us.
The next year, me and the other finalist had to actually take over commish duties, as the experienced owners bellyached and dropped out one by one as the 1993 season approached. Fortunately, we were able to fill the league with good, competitive yet courteous owners. I've now been running this "unified" league since 1993.
