If he can be healthy and return to the form he was at in Houston in 2008-09, this is a steal. If he can just provide a three point shooting burst off the bench, he will be a good signing.
But don't forget he couldn't pass a physical when first trying to come back from Greece. I think he has back issues, which, as we all know, can be long term.
Nice signing for the minimum. Hope he works out.
