In general I'm just not a big combo guard guy, but they can be valuable. Big wings just have a higher floor of usefulness on defense and a higher ceiling of potential dominance in the playoffs, so I get why most of us have boners for them.
The Jazz will need some off the dribble volume shooting from a guard position at some point. Right now no one on the team provides that other than Clarkson, and he is aging and not super efficient at it.
Keyonte and NSJ were both highly regarded as ball handlers who can shoot pre-season and they haven't really planned out.
NSJ has been injured and when he's healthy he just doesn't look good enough to me. I love his energy on both ends and he makes some great passes, but he is allergic to contact and lives on tough shots. I think he could definitely drop to late lottery to potentially out of the lottery
Keyonte has had big time games vs good competition, but he's been inconsistent. He's a prototype combo guard though and he's going to be a good shooter at the NBA level. He draws fouls and flashes playmaking ability. He's probably going to go top 10 regardless of tourney performance.
To say Danny Ainge and the Jazz staff would unequivocally not draft either is poppycock.
