I'm a big Giorgi fan and would love nothing else but to see him be successful at the NBA level, but this is a bit of a stretch IMO. He is an elite teammate, personality, and work ethic. There probably isn't a better "glue" guy that Giorgi. Not shy, funny, and overall wants what's best for the program. He's a fan's dream and a great story.
However, as an NBA prospect, it's tough to see it. 6'9" let's say a true 240-250lbs when he leaves. His game will have evolved to where he will have a good all around game. Stat sheet will say: 20 points, 6 rebounds, and 3 assists per game by his senior year. Can score with a soft right or left hand and can shoot the 3 at a 31% clip. Not great, but keeps defenses honest. Is mobile, but not an elite athlete and doesn't play above the rim. That to me reads like a professional athlete abroad in Europe, Australia or China. Think about the position he would have to guard. He's a 3 in the NBA. Zion, Draymond, KD, maybe even a Bobby Portis...who is even taller and bigger that Giorgi. Just look at Tyler Hansbrough...Amazing college player with much the same game if not greater than GB and he had a tough time in the
I really hope I eat crow on this one, but I'm not sure your enthusiasm is founded.
