Cade has one big thing he needs to fix to become great and he does it by doing 3 smaller things.
The big thing is becoming more efficient. 53% TS% is a joke, like Killian Hayes is the punchline to that joke. 57-58 would be better, but the elites can get it over 60%. This is by far the #1 thing he needs to fix.
The three things that can help with that? Finish at the rim better. Develop more of a mid-range game. Draw more FTA's.
Finishing at the rim is self explanatory. He gets to the rim a lot but shoots a low percentage in the restricted area and in the paint.
Developing a better mid-range game would help. Yeah its an inefficient shot compared to the 3PT shot or dunk. But it is the shot defensives give up the most, so good players need to hit it. Elbow extended jumper and a little floater would do wonders to help his game.
Drawing more FTA's is probably the biggest thing he needs to do to improve his efficiency. When you draw a shooting foul that shot doesn't count. If he can turn 2-3 of his misses into fouls, you are taking those off of your box score and its much easier to score at the line. All that means increased efficiency.
