Danny's going to have to be blown away to make a trade. Disregarding the fact that there's a strong chance that Danny doesn't really want to trade Rondo to begin with; even if he did want to trade Rondo, there's absolutely no rush to do so. He might as well hold onto him and see what he can get for him this summer or next trade deadline when he's further removed from the injury.
And generally speaking, I think that'll be Danny's entire attitude towards this trade deadline. Unless there are very strong deals, there's no reason to trade anyone. Even with guys like Humphries and Bradley, Danny can always work sign and trades this summer.
