2014-15 was expected to be a transition year with the loss of E.P.
2015-16 was expected to be a year of stability.
In my opinion, Marlin made his mistake by playing too large of a rotation at the beginning of the year. He should have reestablished their returning groove first, and worked the supporters in slowly.
It didn't happen and they never got the groove back that you would expect with a mature returning roster.
