Why would anybody assume that we can sign Casspi to a "cheap" contract? And what is meant by "cheap," in this context?
Let's face it, we used each other here: he needed us to give him a second chance, when it looked like he was on his way out of the NBA. But he proved that he can still play. He wanted to show that he can be a team player, that he can still be productive in the NBA when playing a role, and that he can accept coming off the bench. And he succeeded; he's earned a shot at another multi-year NBA contract. For how much, and for how many years, I decline to speculate. But my point is that he doesn't owe us anything else. We both got what we wanted: just like he needed a second chance, we needed a veteran backup swingman, on the cheap.
And now, he's shown that he can still be a productive backup swing, just in time for him to become an unrestricted free agent. I'd be fine with Casspi coming back, but it seems to me that some people are making it sound like, if he doesn't come back, it's going to be because of some failure on the front office's part. It's not as if we hold his rights, and he can only go if we let him; he can go, all on his own.
