Do what you think is best but Hoood WILL get a huge deal from someone. If Tim Hardaway get it then Hood will easily. Letting a dude go into RFA gets you a better deal 0% of the time. If you aren't sure about the future of Hood and Exum then fine see what happens, maybe keep one who you'd end up maxing.
Super risky move is to do the extensions right now for the best deal and pray. Could totally cripple us if we give Exum like $12 million and then he still stinks we are screwed.
Decent move is to let them earn it and then midway trough the season re-evaluate. But they will only get more expensive if they are 'earning' extensions.
I think if I could get both for $30 million I'd just do it. **** it. I'm optimistic. If you wait and they earn it then it costs you $10 million extra minimum.
