The benning disappointment has to do with failing to meet the goals he set. Had he not wanted to trade up, or get certain things for Kesler, there wouldn't be a problem, whether we agreed with his decisions or not.
But that fact that his objectives were made public knowledge and he failed to achieve any of them, is the root of our discontent.
Virt is a power forward, there is higher rate of bust with that particular sub-group of players, It also appears to be a reactionary pick, trying to keep up with LA. "Follow the leader" team building doesn't have a very good track record either.
So there you have it, that is the basis for the current malcontent.
