Gordon Hayward.
Anything less would be a failure. We saved our cap space for this. We passed on Markelle Fultz for this, I'd be irate if we don't get one of the top free agents available, and he's the only one left.
And don't give me Paul freaking Millsap...
Do you really think Ainge preferred Fultz but opted to trade the pick to clear up space for Hayward?
I do think it was a significant reason, yes. I think Danny reasoned somewhat like:
1) Fultz is only a slightly better prospect than Tatum;
2) By trading down, I can pick up Tatum while adding another asset;
3) Also by trading down, I can pick up extra needed cap space for Hayward;
4) 1 + 2 + 3 equals more overall value than just picking Fultz at one;
5) Thus, I should make the trade down in the draft.
Danny is very utilitarian in that regard, for better or worse.
