I think the idea is that 33% 3point percentage equates to 50% 2pt FG% which means 2pt shots are worth far less especially since fewer players can score 50% from 2. The formula is to multiply the percentage point by the point total. Both ".33 x 3 pts" and ".5 x 2 pts" equal to 1 .
Of course, you can do this in reverse, especially if that center can run the floor at an adequate speed so that enough possessions are secured. Suddenly 55% 2pt FG% equates to 37% 3pt shooting.
Since Edey appears to be a 60+% 2pt big man due to the fact that he's so tall and has strong footwork/good hands/mobility to be a solid enough scorer whether in college or in the NBA, that puts him in great company.....on par with the likes of Shaq, Jokic, Giannis, Kareem, Wilt, Kevin McHale, Dwight Howard to a lesser degree, sophomore Greg Oden, Ayton - especially when he puts in the effort, and Jonas Valanciunas.
We'll see what type of player he ends up becoming but going by that list, he is very likely a certified NBA starter with untapped potential and good playoff capability.
