I'm not entirely sure if you're referring to "in-game stories" (e.g. statistical developments of note) or "out-of-game stories" (e.g. fictional storylines created by the people who participate in the league). If it's the latter, give
the PEBA News Archive a browse. You'll find storylines galore.
The latest involves the investigation of
Julian Nizinski, Private Investigator into possible mob ties for
Michael Czosnyka, new GM of the
New Jersey Hitmen. My understanding is that this is to be the first part of a continuing series.
