That teams at the top of the draft are targeting Brown only confirms everything I have thought about this draft. Those teams obviously believe Brown, as currently stands, is better than anyone's ceiling they could draft. This is a crap draft. Don't trade Brown for anyone other than Zion, and we all know that isn't happening.
or they see the Celtics might blow it up and want the cream of the crop
No, it's because it's a crap draft. Teams at the top of the draft seldom go looking to trade those picks unless it's to pick up an established player they think is much better than what they could get in the draft.
GMs get locked into players in the top of the draft and usually way overvalue the pick. It's great to be able to do so because those GMs are usually GMs of terrible teams and can sell the fanbase on the potential of their shiny new rookie.
Do you think the Knicks, the Pelicans or Cavs would have an easier time selling to their fans and team a brand new rookie with supposed loads of upside or Jaylen Brown, who if you look at his entire third season may have stagnated or regressed?
The answer is very easy. They keep the pick if that player has loads of upside. But, if all the players in that area are believed to have a lower ceiling than Brown's current play level or Brown's upside, they are going to trade that pick.
