I know how important Green is in the Warriors and he is one of their best defenders but to ask for a 10-year contract? I don't know if it will happen because the Warriors will not get any benefit from it in the long run. That's too much I think and the Warriors can't even give him a max contract (for now). He is 32 years old and a few years from now, he will be in the post-prime period and his performance will slowly decrease thus, it will not help the Warriors so it's a no-no for me and maybe it would be better for the Warriors if they will just trade him if Green will push what he wants. Kinda hurt but it would be beneficial to the Warriors management.
There is no doubt about Green's importance in the team because he is a valuable asset to the team, but he should be informed enough that there's no team in the NBA who will grant him that long contract. I mean, he is quite older already and he won't be producing the same production he did in the years to come because of that age, he should know by now that it is the reality in the NBA since then because it's a business in the first place.
