Under-achieving and lack of dedicated interest by myself.
This last up cycle saw me miss the playoffs as many times as I made it so I didn't make enough right moves to pull down more rings. Mind you, while Phen0m was here, that was always going to be difficult. Plenty of good owners on the NL side, and DTV has been particularly strong lately.
I did manage to win the last title by a NL side, which is sad in and of itself.
