I still would select Green. Yes it is another guard but really need talent on offense and to me Green can potentially be a star. I prefer Mobley but if Green is there, I take him. I would then try to get a mid-late first round to pick a tall PG or a wing player that can help our shooting.I think Mobley is a very good fit for the roster. Green and Suggs aren't as much. I think Koby might have overvalued what he could get for Sexton and now that the offers have come in, they could shift on the thinking of how they will approach building the team out.
Let's say Green is BPA, is the impact of Green and the package from Sexton going to outweighs something like #5, #8, and keeping Sexton.
I think we would have a solid rotation if we trade down and get Barnes with Bouknight, Moody, or Zaire Williams. Even Barnes and Jalen Johnson would be really evaluate the amount of talent this teams has even if they are somewhat overlapping in talent.
