they won’t pull that trigger.
I don’t think Denver helps themselves out at all by getting Noah for Melo; look at their front court depth already (despite them being banged up):
Nene, Birdman, Balkman, Harrington, Shelden Williams, Kenyon Martin. Even Malik Allen, whom is a FA, could be back there.
Perhaps it would be safer to think they would pull the trigger on a multiple player deal, but who else would (could) Chicago throw in?
