I'm sure they'll pursue Griffin. Maybe they'll be successful, although they will have to figure out some cap magic to have the room for him.
But the key thing is that the entire point of Ainge trading for Griffin, if you believe that there was ever anything to the story, was with the cap room to extend Griffin, so that he doesn't leave as a free agent. Ainge isn't going to open his piggy bank for someone he thinks might leave.
At the same time, Doc has a very competitive team, and he's not trading Griffin for peanuts. So there is still no agreement coming any time soon. It's far better for the Clippers to keep making a run at it with this year's team, and figure out Griffin next year, than it is to trade him. Doesn't matter if they lose him for nothing.
Now, if the Clippers are somehow around .500 in February, maybe things change. But before the season, it would be stupid for Doc to trade Griffin for anything less than a great package in return. And since there's no commitment Griffin will stay, it would be similarly stupid to offer a ton.
Just not happening, for like the 10000th time.
