Ford:
"The Celtics love Jabari (as do most teams) and we've had him as the No. 1 pick for them. But Embiid fits more of a need and has a bigger upside. Ainge has drafted on upside in the past but last year I know he loved Giannis Antetokoumnpo but didn't pull the trigger on him and instead took the much safer Kelly Olynyk. So maybe Ainge isn't quite the gambler we make him out to be."
Ouch.
In a weak draft, Ainge may have felt the best play to make was to go with the guy who had the best chance of being a useful role player.
Right now, the Celtics are on track to select pretty high in the draft, which means Ainge will be able to take a guy with a lot of upside who is also a fairly safe gamble. None of the guys in the top 6-7 has major bust potential, as far as I've been able to glean.
Even Embiid, if he never really improved from what he is now, would be a nice player, though not a great one.
