The ONLY reason to take a draft pick over Giddey would be financially, with Giddey getting a new contract after this coming season.
If based purely off basketball, the Bulls need to add play making, Giddey brings that. He a very solid rebounder and when playing as primary play maker for OKC (SGA out) he played very well. I don't see many players in this draft that will have the same impact in that role this season
He's still 21 and is younger than a lot of this years draft class.
His shooting has improved each year in the league (small samples), but his FT % is very reasonable after a poor first 18 months in the league.
He was put in a role this season that did not suit his game (understandably with SGA and J-Dub's star qualities), and still was a great team mate and professional.
Everyone wants to highlight the Dallas playoff series and yes he was played off the floor in a position we will not be asking him to play. OKC themselves didn't play well in that series either. You can't blame a guy that's playing under 20 minutes a game for that series loss.
No-one mentions that he played fairly well against the Suns and hit 50% of his 3's in that series.
I think this is a very good trade. If the FO finally heads in the direction that this trade indicates, at least it's a chance to move away from being a perennial play-in team.
Josh, Coby, Ayo are a good young guard rotation
Sometimes a player's greatest challenge is coming to grips with his role on the team
