While I love this move, would like to add a little note of caution to folks who feel that he shall be on his best behavior since he is playing for a new contract.
He was playing for a new contract in Dallas too. That didn't work out too well. While we can hope that he has learned from that lesson, Rudy being his friend helps, Karl will allow him a little more freedom, there is a good chance that he shall implode again. Dallas gave him a winning environment, proper structure, and vets with championship experience. We are giving him a rookie (almost) owner, rookie GM (even though he seems to be doing well so far), a coach who is at odds with the star player, and a team that has seen more dysfunction that winning.
So, yes, I have my reservations. Despite that, I'm enthusiastic about the move. We weren't going anywhere before these moves. We had to try for a home run, and Rondo signing is as close to one as we were going to get. If we start the season strong, all the stories about FAs not wanting to come here, stories about Karl and DMC fighting, Vivek meddling, etc. will soon be forgotten.
It's also good that we are getting folks who have been with successful programs, and have even won championships. Now we need to sign a decent backup big (hopefully, again from a winning culture, and no, not David Le, even though I don't dislike him as much as lot of other folks), and for Ben to grow big time. We need him to start hitting the outside shot consistently, and use his athleticism to be a lock down defender.
