I think we've heard this story before. Trading a draft pick for an impactful vet never seems to be what the trading partner wants to do. I guess if we got into the top 4 we could get a top of the mediocre tier starter like another Collison, but it's pretty unlikely somebody is going to give you a top 10 player at a position for a draft pick. And if it's trading a potential All Star (top 4) for a Collison type, no thanks.
My memory is not clear, but I do recall many years where "the discussion is" that a Top 8 draft pick can be traded for good vets.
Here's some examples from our recent history:
* In 6/2011, Tony Parker was reported as being entertaining offers by the Spurs (seriously, they were down on Tony that off-season. I forget why). The Kings were in the mix to trade them high draft pick for Parker. The majority of this forum said no to the deal (if you can believe it!). Parker went on to cement his place on the Spurs with a dominant (amazing) year.
* 6/2012 Pao Gasol was on the trade block by the Lakers after being scapegoated for their non-success. We reportedly could get him for the #5 pick and taking on his big salary for those remaining years of his contract. Not only did most KingsFans not want to make the trade, but the Kings decided to keep the pick and select the most sure-bet in the lottery, the guy with the most easy-to-translate-to-the-NBA-game, Thomas Robinson.
How'd that work out, again?
* 7/2012, Kyle Lowry was traded for a future first-round draft pick + nobody.
These are just some examples that caught in my memory - I'm positive many other KF's could relate more examples of when a draft pick has been traded for an impactful vet.
