I don't even think the Lakers will take a chance on RR now---I bet Goran Dragic ends up there....Knicks are a team Stupid AND Desperate enough to give Rondo Max money.
There needs to be multiple teams bidding on him for Rondo to have any form of leverage. I am not sure who those multiple teams would be. Also another reason a team like the Knicks have overpaid for players is because they can sell them as Stars. I am not really sure you can sell Rondo as that right now. He has a special place in our hearts as Celtics fans (or at least in some of ours), but to the average fan he really hasn't been relevant in quite a while. I have been continually surprised by contracts in the NBA so anything is possible. However, it just really is hard to see Rondo getting a Max contract from any team right now. He hasn't been an all star since 2012-2013 (which he didn't even play in because he got hurt) and has suffered a number of injuries coupled with well publicized petulant behavior.
I'm not sure who those particular teams would be, either, but I can think of one that would be perfect for him, and that's the Indiana Pacers. Bird's a big fan of Rondo, and they need a point guard. Pairing him with Paul George could be like what happened when Red got DJ for Robey, imo, plus, Rondo would easily speed up the tempo, which is apparently something that they're looking to do next year. Please god let this happen, lol.
