Not saying that we won't pick Tatum. I get the appeal. But....
I take absolutely no stock in the report, not that they didn't tell him this, but the veracity of the opinion. Celtics have nothing to gain by letting the universe know which way they are leaning.
It is GM's job to stir as much possible interest in the pick as you can. You don't do this by leaking out who you plan to take unless: (i) they are trying to stir up a market for Tatum, which is doubtful, no one else has reported anyone wanting to trade up to get him, or (ii) it's a misdirect where the intent is to draft someone else, probably Jackson, maybe Isaac.
