If you don't trust the Keeper enough to ever play him it's better to replace him. Considering that they were playing such poor Keepers as Bono and Westberg ahead of him even when injured, I'm going out on a limb and say he's still far from playing at this level, and probably will never play at this level --- yet another terrible pick-up. Time to cut our losses.
You may have missed Mike Forbes post above quoting Michael Singh. Michael Singh says we only need to have one unprotected (because home-grown players aren't eligible to be drafted). I don't see homegrown players in your calculations so you should update them for that.
