1. resign marion for 8/yr for 4 years
2. trade Bosh
straight up for KG (with POB as filler)
3. sign delfino, rasho, paker and wafer
Jose + Delfino + Marion + KG + Bargnani
Parker + Waver + Evans + Rasho
This lineup can compete for a title for at least 2 years. 3 years from now KG is a FA, we can trade marion as an expiring contract and reload.
I can't think of any other realistc scenario who could give us more short term results while keeping our mid term flexibility.
