The extension cost of Clarkson is actually lower, $8m per year, best ranking 124.
Best ranking is calculated overall, regardless of position.
For the other players:
McCollum $29m
Derrick Jones $7m
Niang $6
@frankbullsfan Could you kindly confirm that you do not want to re-sign the 3 players above and extend Clarkson for 2 years at $8m?
