It really is a tricky question. If we want to give up on our current roster, the picks are our best bet. We will hope for the Nets pick become #1 (odds are against that because of the Lottery) and hope there is a transcendent player that year like Lebron or Anthony Davis. Is so happens that neither of those guys got a title on their rookie deals. In fact, what best players on their teams have won a title in their first five years?
Kahwi did it, but he was on a team that already had a roster that had been winning titles. He was more of a final piece than the foundation, especially since he was just reaching all-NBA caliber at that point clearly was not the best player on the team when the season started, regardless of how the finals went. Now that we have Horford, we don't necessarily need a young guy from the Nets pick to be all-NBA immediately, but we will be waiting a year or two before the player arrives and Horford will be a year or two older when that player is only a rookie and underdeveloped as likely a 18-20 year old.
Draymond Green is on his rookie deal, but Curry is the best player on that team and is the 2-time MVP.
The fact that the Nets picks will be at the top of the draft means that it will be less likely that we will draft older players like Green or Curry, which would mean waiting more years for development. Green and Curry were 25 and 27 year old respectively when GS won. Those Nets picks will take longer to develop if they are higher in the draft.
I would avoid talking in such strong terms about those draft picks.
