Recriting questions

Granted that we have actually signed no one yet, but if the three who have announced commitments to us do in fact sign, it makes no sense to me. True, we are losing a 3 (Isler), and the 6-6 kid could be a replacement for him.  But we also signed two shooting guards, and we have those running out our ears. Particularly with the loss of Neighbour, we will be needing help at the post  badly. Granted that Gus and James probably are the starters for next season, but where is the depth?
