In essence I think you really hit the nail on the head in noting that we simply became much too reliant on LCJ. We were not a well-rounded team.
I still can't believe how off I was in my enthusiasm concerning Maishe Dailey. What a gorgeous athlete, ideally built for basketball. And in remembering his impressive skill set from high school, I thought Groce's style would be perfectly in his wheelhouse and that he'd become a 2nd Team All-MAC-caliber player. When that didn't materialize we were never the team I was envisioning preseason.
Additionally, boy was I wrong about Currie. At 6'8"-6'9" I thought he'd be our staring center from day one. When he failed to earn any PT we suddenly became a very small team; our two true post players each coming in at 6'7". (And neither 6'7" guy was a stretch post player, like 6'9" X was, and like 6'8" Currie was touted to be.) So that also threw me a knuckleball from what I was anticipating preseason.
We simply lost too much when we lost three leaders, tenacious defenders, rebounders, and 3-point threats in Cheese (6'5"), Banks (6'4"), and Williams (6'9"). Never were we able to begin to even slightly fill those shoes this season.
