If you could convince me that there's a trade out there that's so good it overrides the pick value, I'd do it. Like if Dumars trades us Herb and a future unprotected pick to us, sign me up!
In absence of that, I think you just play all the young guys and let it ride. And maybe you make the determination that Key and/or Lauri need to play less minutes or miss a few more games. Either way, it's a good thing if our young guys carry us to a point where we win to much. Much better feeling than being kept afloat by vets.
Even if we were competing for something this year I'm uncomfortable with the amount of minutes Lauri has played. And while it sounds odd to sit a 3rd year breakout player...."you know who" did exactly this. 1-2 games can make a big difference wrt to keeping the pick. I don't think you need to be extreme, but also don't be stupid.
I've said it all year, but the less we do now, the more painful it will be down the road. That could painful as in pulling out the tanking extremes or painful as in losing the pick.
