Rondo has dug himself a big hole. It is going to take some humility to get himself out of it and convince a team to pay him. That may prove difficult for him.
I feel bad for him even though most of this is his own fault. Can't know how much impact the knee is but it is not the knee that caused him to shoot 39.7% from the line. Nor is it the knee that made Rondo cling to wanting to play only his way and disrupt a team that was cruising along before he got there.
He could have extended with the Celtics for something like 3 more years at $15 per. I think Danny would have given him that if Rondo would have taken it. If he had, I wonder if he still would have been traded. Probably.
But Rondo wanted to be a FA and will now get his wish. I don't see how his value could be any lower. I criticized Rondo plenty but in the Celtic's heyday, he played hard and made some amazing plays. I hope this is not the last we will see of that Rondo.
