We'd be firing on all cylynders.
We would Have CJ play exclusively at SG, have a backup SG, have a very good rotation at SF with Henderson, Crabbe, Harkless. We'd have inside scoring with Alexander which is something we lack, Davis and Aminu would still get minutes depending on matchups. Vonleh is more of a Center than a PF and Meyers could still play only 20+ minutes but I think he's our best option at PF and should start. We would be able to have both CJ and Dame on the bench at the same time and still be competitive. This means they'd have more minutes on the floor together. Our 2nd unit could be strong enough in the backcourt with Roberts, Montero and Crabbe (for example) and our starting lineup is probably our best lineup at least offensively.
So yes, I think that's what we need. This could be like when Maresse Speights got injured for GS and Festus Ezeli made the rotation before last year's playoffs.
We need this boost, get all our weapons in sync before the playoffs and hit it in stride
