This is such a bad mentality to have as a franchise. It's almost yearly now that there's 1 or even 2 guys in the 2nd round that end up making a real impact from the 2nd round. They aren't "throwaway pick". It's assets and a chance to find a huge boost to your team you weren't expecting for a bargain price.
And its not just the 2nd round picks. Vlade was asked if he shopped around the cap space at all or looked to make trades. He basically said they didn't look at anything and stuck to their plan and were happy with their plan.
Look at the 2015 draft 2nd rounders:
Montrezl Harrell
Willy Hernangomez
Richaun Holmes
Josh Richardson
Pat Connaughton
Norman Powell
There are guys to be had in the 2nd round that can give you anywhere from average bench contributions to full on playoff level contributions. It's rare but you don't just go drafting Wet Biscuit McGee out of Vacaville community college because you don't think that the 2nd round matters. At least give yourself a shot. If someone gives you a lottery ticket for free, you don't just throw it away because the odds of winning are low. That's kind of what the Kings did here.
