I am not sure for 100% but i believe that i set gdp for yor LI, maybe that decided it and that info is also probably lost...
Maybe you should check the replay (finally it is available), you lost your pf due to an injury. Also as a experience player you should know the influence of home crowd in final play off game is crucial in the bb engine... After all your sf spot was very and pf also after injury opened the hole in your team.
