Well Rondo has every reason to have a great year this year. He is now 2 years removed from the torn ACL (Ive heard a lot of people say it really takes 2 years o come all the way back, or as close to all the way and you can) and he has a 1 year deal with the Kings. He is 29 so he knows playing well this year is probably his last shot to get a big pay day (not that 9mil for one year isn't big.) People are really down on him now and I think Rondo is the kind of guy that holds grudges and uses them to motivate him.
I think you can say Dallas quit on Rondo just as much as you can say Rondo quit on Dallas. In that last game against the Rockets Rondo is clearly p---ed off. But I think he is p---ed off because the team is losing and he is getting beat by the much bigger James Harden. There is a difference to not playing D and getting beat by one of the best players in the world who is also much bigger than you. A lot of guys would play off Harden and just hope that he has an off day. Rondo was playing right up on him and very physical. Ideally you would have your 2 guard defend Harden and Rondo could have been on Terry. I think Rondo ws already upset at coach Rick for not letting him run the O and getting beat by Harden added to his frustrations. At this point Rondo must have already known there was no way in the world he wanted to resign in Dallas. But Rick benched Rondo and lost the series. Rondo didn't refuse to check into the game. I feel like that fact is lost when people are so quick to say Rondo was the one who quit. Really Dallas was pretty foolish to make the trade in the first place if they were not going to let Rondo run the O. In Boston Rondo hated having to have Doc call the plays early on and he slowly earned Doc's trust to the point where Doc let him run things for the most part. And they have plenty of tiffs (one story has it that players had to hold Doc back from attacking Rondo.) So if you know this about a guy, why trade for him in the first place?
I can give Rondo a pass on his play sense the ACL. He still looked great is flashes so I think the talent is still there. What we don't know is how good Sac will be. We know Rondo is not really a fan of playing meaningless games. He got spoiled early on when we got KG and Ray in in 2nd year. But he is going to need to suck it up for 1 year on the Kings if he wants to be able to land a long term deal on a good team where he can run the O. That's got to be his plan A, we will see if he can pull it off.
