In this scenario, we give Eugene more minutes and grab another big from the G or from FA. In this scenario, we likely get salary filler or a TPE attached to maybe a few draft swaps, a late first, or a handful of seconds. If we are lucky maybe we get a raw prospect. We also have a better chance at the #1 pick.
Gafford is a microwave player, but not the longterm solution for any team at big. His optimal role would be off the bench for a contender providing energy, rim-protection, and rim-running in spurts. Kinda like a worse Javale McGee.
Realistically age doesn’t matter. Neither Gafford or Eugene should be long term centers for us. If we want an older big it should ideally be a great pick setter and locker room guy.
