Since I started this thread, I have continued my Fultz research. I watched a full game and a half of action, I read more, saw videos of him dunking, and the truth is I'm higher on him than I was when I started this thread. He's really smooth, he's really versatile, he moves better and looks more athletic than I first gave him credit for.
All that said, I still hope Danny is at least exploring trade options for the number one pick. If there are rival GMs out there who are as gaga over Fultz as most Celtics fans are, we could get quite the haul back. If, for example, the Bulls were willing to trade Jimmy Butler for the rights to Fultz, I would be very interested.
As good as Fultz is, I just don't see him turning into a once-in-a-generation type talent. It's exciting to have the number one pick. I certainly hope Danny is keeping multiple options open for how to build the next Celtics contender (sooner, rather than later).
