Ultimately, I think Brad is fine rolling with what they have (maybe Griffin doesn't retire and comes back on a vet. minimum), and his plan is to use a bunch of the future 2nd round picks to acquire some cheap PF/C at next season's deadline (or buyout market)
Lets be real, all they care about is playoffs which is completely fair. They can survive the regular season with the likes of Kornet, Gabriel, maybe Griffin as depth.
