I'm thinking we sign Gay for a few seasons.
I don't know who else would be able to sign him - maybe DL is driving up the price for Miami's Johnson so we can get Gay. As much as they would love to, Miami can't get Gay if they have Johnson. If Gay signs with us and plays well it will be a steal and all free agent signings will be judged with: "Yeah, he's a good player, but would signing him bring us Gay value?"
Plus I think Gay and Joe Johnson would play well and would lead fast breaks. I would expect a Gay-Johnson hook-up to be on the regular. Maybe not as exciting and Steve Francis and Mobley but still epic.
