I mentioned a similar scenario in another thread. I wish we could pull this off.
I don't think it's completely far-feteched as I actually think the Lakers might consider this as a trio of Pierce, KG and Kobe for one final ride could be a great narrative for Lakers fans.
For the Celtics, we land the best center in the NBA and a franchise player.
The part that I think might make this hard to imagine is that if the Lakers entertained sign and trade scenarios with Howard, they could probably receive alot more value than just one year of Pierce and KG.
BUT, fun to think about nonetheless.
