I think we absolutely have to sign him now. There might not be another chance to get anyone else. If Smith becomes available, and Moore is not working out, we cut him and sign Smith. Or there is even the chance that we use our two roster spots on both of them while we (still) wait for Marbury to be bought out. That would be the ideal situation in my opinion, as we could then evaluate both of them, and cut which ever one is providing the least, when Marbury finally becomes available.
