This is quite the conversation. I will throw my 2 cents in. When comparing Leonard's production this year to George's production last year, it is ridiculously close. The biggest difference was that George had a 28% higher usage rate. But that doesn't signify that he is better, just that Indiana needed to rely on him more. The ultimate questions is whether the spurs think that Leonard will continue to function at this level (or improve) with a higher usage rate. The other chance is that running the ball through him more, might decrease his efficiency. Ultimately we won't know that until it happens. But the spurs will have to pay for what they believe will happen. If they think he will help carry a team, then they will give him the max. Teams are allowed two super max deals. So why can't he get one even if he is the #2 guy. If they don't think he will ever be more than just a number 3, good starter, ultimate role player, then they will let him walk for more money or they can try to convince him to stay for less.
I am not saying that Leonard is as good as George, I am undecided. What I am saying is that teams do hand out max contracts based on potential. George got his deal after he put up 16.4/7.3 (per36). So it would not be totally ridiculous to see Leonard get offered that money after a 15.8/7.7 (per36) season. I personally hope the spurs wait one more year, but I will not second guess them if they offer it. They get paid a whole lot more than I do to make these decisions.
And anyone who thinks a max deal would fracture the locker room has not been paying attention to this organization for the past 20 years.
