I think he is a good player to develop. He has good length and big game experience. I've read articles that McCaw is seen in their organization as their future replacement for Iggy.
We have a roster spot open and offering him a 3 year 4-6 million per year offer sheet won't hurt us for the future. At worse he becomes trade filler. At best we steal a rotation player for cheap. If they match, you at least make Golden State pay more luxury tax and it could effect what they offer Iggy, Draymond, or Klay.
Also I think it's a good negotiating tactic for the future with restricted free agents. If you take the QO like Hood, we might go out of our way to get someone at your position to take minutes from you. Hood can bet on himself but we will hedge that bet on our end and we won't gift wrap you minutes.
