I suppose that another reason why some would consider this trade is that KG is still a hot commodity..right now..this season.
Great Trades are made while the iron is hot.
In two years KG would be 35. I really don't see him playing for another team. He may just pack it up and retire here in Boston.
Still, though...striking while the iron is hot won't bring us Banner 18 or 19, even with Bosh.
Bosh has out of this world number for points and rebounds right now, but how many blocks? Steals? Does he intimidate anyone? Would he ever? Would he talk to teammates on Defense? Would he be able to get the ball to Perk down low? Ever? Low post threat if/when we needed it?
Doc, Thom Thibedeaux, Clifford Ray could (Maybe?) teach him, though.
KG's importance to Celtics is incredible. IMO I cannot think of Anyone in NBA right now that we could trade for him that would guarantee Boston a ring this year. Anyone.
And the Raptors are 3 and 4. Bosh has Great Numbers, but his team is losing.
