The issue with most of this (and I agree with a lot of what is said here) is the difference between the two sports (NBA and CBB). In a ranking system looking for college production, Kofi would be #9 in his class and Coleman Hawkins 84th. Using a system looking at future potential in the NBA, Hawkins would be 27th and Kofi 98th.
I'd prefer a system that ignores NBA potential (which is really just ranking the players who have exceptional height and length for their skill set) and simply looks at potential college production. Ranking based on height is what puts Carsen Edwards 118th, and what good is a system that puts Carsen Edwards 118th?
