I feel like SF's of Green's caliber are a dime a dozen. Beasley, Jeff Green, Marvin Williams, Ariza, Richard Jefferson, Stephen Jackson, Batum, Gerald Wallace, Marion, Prince, Maggette. All players who are considered "good" players, but none will ever be all stars at their position and all make too much money considering how many equal-better players there are at the SF position. There are at least 6 NBA players (Lebron, Melo, Granger, Iguodala, Pierce, Gay) inarguably better than those on that list. And I didn't even mention Deng and Gallinari or fringe SF's like Joe Johnson and Josh Smith.
You can't pay 8-9 mil per year for a guy who is so relatively weak at his position. Considering those players named and also the potential rise of Kawhi Leonard and Paul George, does anybody think that Jeff Green will ever be a top 8 SF in the league? I'm curious if he'll ever even be top 10.
I say 3 years 20 mil (or 4 yr 25 mil) MAXIMUM or let him walk.
