At the end of the day gordon will be a celtic imo.
He is a sf and the magic already have tobias harris
And they also have Moe Harkless, who isn't great but still very young and a good defender.
I think Danny and co are looking at Embiid and Randle with screws in their feet already, and thinking that a lighter player like Gordon will likely be less injury prone over the long-term, which will give him the draft edge over Randle.
I'd still rather draft Embiid and I bet Danny would too, but there are so many elite prospects this year.
