I can’t see how Kriisa is anything like Curbelo in any way. Curbelo was waning since his first season at Illinois. Curbelo also had no shooting ability at all and was a headcase out there, constantly pouting and getting in his head.
Kriisa sounds more like he’s got a killer instinct, can shoot extremely well and has run the PG spot at a major top 10 team. I wouldn’t be surprised to see him in 2-3 guard offenses at times as well with his ability to shoot and play combo.
In addition Rick will have him learning to play defense and a matchup zone like Rick runs is perfect for his style. Compares more like a Daniss Jenkins to me rather than Curbelo.
