We seem to standing on the side of the road while everybody else makes a move. Which leads me to think that the other teams in the NBA think we have no real assets. Even Rondo is tainted. This is not good to say the least.
I think you're reaching an incorrect conclusion here. Rather, I think the answer is that Danny just isn't interested in the players in question, or isn't interested in them at the price being asked.
With Asik, my guess is that Danny wouldn't put #17 on the table, so Houston went with New Orleans' offer. Regarding Afflalo, we obviously could have trumped that deal, but decided against it.
I think that that suggests that Danny is going a different direction than the "win now" route. I would expect that this means we're rebuilding in earnest.
