I sincerely hope he is not finished. Since I've been following the nba he is my favourite player to watch. I loved him when he was playing for us and I still follow his games to see his production.
Even with flaws in his game, specially in the modern nba, he managed to play in an awesome level. He was an elite PG despite not been able to shoot from distance. Every opponent he faced knew he couldn't shoot and knew he would want to penetrante, but he still torched a lot of games.
I think his career could have been a little better, maybe with one more title and a few more all stars appearences, because he is a very talented and intelligent bball player, but I think he's having an amazing career so far. A career he should be proud about. I am very thankful for what he did for the celtics and I can certainly say that his style of play played a big part on me becoming a Celtic fan for almost 10 years.
So, I thank you Rondo for the moments of joy you gave me and for being a big reason to the birth of a brazilian celtic fan! I hope you find a good place to play and wish you well.
