I started thinking this fairly recently, but is it even a guarantee that Duncan gets a 5th year?
He is a guy that has to be on his shot the most and off the least on this roster. I think that is a statement that everyone can 100% agree on.
I think its pretty clear that he can be a extremely good shooter (at times), but will continue to struggle on the defensive end. I am sure small improvements in certain area can be made on that side of the ball, but he will likely always be a guy that will have many more misses than hits on defense.
But if he is not able to consistently hit shots, there is no way else to describe him other than a liability on the floor.
His role now is probably what he is more suited for - a guy off the bench that comes in to make shots, but he actually has to make them. Also, when he becomes hesitant to shoot and starts to pass up shots, then his value on the court and to the team becomes less and less.
Maybe others feel the same way or different on this. Feel free to discuss But unless some consistency starts to form, I think there needs to be a lot more production from a guy with his role going forward.
