Don't let the size fool you. Deivon is an elite rebounder at his position/height. Averaged 6 last year and had six double digit rebound games. Kadary also averaged 7 rebounds. We would be an elite rebounding team from the guard spots. Outside shooting would be my concern, but I also think its fair to expect the returning players to improve.
I'd also say Kadary is a pretty massive talent upgrade over Dingle. Kadary could be BE POY preseason. Dingle won't get a preseason vote to make a team.
Also think Amase is selling Pitino short in that, we'll probably still be in the hunt for Mitchell and other starting forwards if we miss out on Omier.
