John Hollinger has his metric-based free agent value list up at The Athletic:

Coby White no. 17 at over $18.5M And Nikola Vucevic, who I read elsewhere deserves to make what his old salary was, isn't even listed so is at best just under $15M

Now this counters the internal Bulls front office analysis for Vucevic, which measures games played + double-doubles = $25M
