In three seasons as a King Rudy has averaged 19.5 PPG (on 46.5%/34%/83% shooting) to go with 6 rebounds and 2.8 assists.
He's on $13M a year, which is an absolute bargain in this salary cap scene. Even after guaranteeing Amir and Jonas, I believe we should still have the cap space to absorb that contract.
Rudy G is no superstar, but he's a 6'8" wing with a 7'3" wingspan and very impressive athleticism. He can play three positions at a stretch (SG through to PF) and he can straight-out score.
We are a team desperate for offence.
We could play small with a Gay / Horford frontcourt. Or we could start Gay at SF and go with Crowder/Horford at PF.
Or we could trade for Gay, re-sign Sully for one year, Start Gay/Sully and then bring Crowder off the bench as a super sub. That would give us:
Thomas / Rozier / Jackson
Bradley / Smart / Rozier
Gay / Crowder / Brown
Sully / Olynyk / Jerebko
Horford / Johnson / Olynyk
Or we could start Gay and Crowder, bring Bradley off the bench.
It gives us a lot of options, and if we can trade for him without giving up a core player, it's hard to say no to that. Of course this assumes that there are no start players available (e.g. Cousins) and we are settling for a backup option.
I know not everybody will be a fan of the idea, but the man can play, he can handle the ball and he can score.
