A single top 5 is definitely more valuable than #16, #28, Brooklyn's 2016 (prob 12-18).
Top 5 picks offer a reasonable chance at the next star of the league. Those late 1sts more often than not result in players who never make it in the league. Top 5 pick would be far more valuable. That puts teams like LA, NY and Philly ahead of us in any trade race.
Trading for a star is unlikely. Marcus smart, Sully, 16, 28, nets 2016 is prob an intriguing package though.
It all depends on the draft class. In last years draft class, you had three guys with top player potential. Would you trade Cousins for one chance to land the next Anthony Bennett, Oladipo or Noel? And get nothing else in return? A top 5 pick isn't necessarily better than our war chest of picks. It's only better if the next LBJ/KD/Davis guy is in the top 3, which I'm not so sure there's one of those kinda guys this year.
The Knicks can't outbid us unless Cousins really wants to go there and forces his hand. Same thing with LA. They don't have enough assets. Philly? Maybe. But if you were a top 20 player why would you wanna go there? The magic? Maybe.
But if your Sacto, and your gonna be in the lottery after trading Cousins anyway, I'd want a few young guys on team control and a larger number of draft picks that are probably gonna be in the 8-20 range. Your getting your own high lottery picks too, getting all the picks from us gives you multiple chances at the next 2nd tier (Below KD, James, Davis types) star player.
If NY ends up with the 3rd or 4th pick, there's no guarantee another GM will find more value in that than 4 or 5 early-mid firsts, a few early seconds and a couple good young guys. Much more value in our package. What happens if you miss on that #4 pick? You get nothing for Cousins, that's what.
