Teams can ask anything they want, but getting it is a different story. First the Rockets were asking for 2 first rounders, now they are down to one, and what they settle on will be something less than that.
All it took to get Asik was the money on his contract and cap space so I don't see why anyone would consider giving up a first round pick for him unless you think he is that last piece on your championship team for this year. If your team is that good, you probably don't have 8mil in a contract you want to get rid of to flip to Houston and you certainly don't have cap space to just take his contract.
As far as Asik to places like Portland or New York, Asik clearly doesn't want to be a backup. If he isn't going to be a backup for Howard, he isn't going to be a backup for Aldridge or Chandler. I know Asik can't stop a trade but nobody wants to trade for a guy who isn't going to be a happy camper, especially if you want to make some sort of playoff run.
Finally, he isn't that good. He just isn't. He can't hit free throws, he isn't good offensively, and isn't dominant defensively. He is a piece that probably costs more than he is worth.
I'd do a deal around Bass, and one of our shooting guards not named Bradley or Crawford and throw in a second round pick. That is it. If Houston can get better, good for them. Stick with our plan, play the year out and get the 20mil off the books for next year.
And by the way, Bass is way underrated. How many bigs do you find who can reliably knock down mid range jump shots, can switch off to small forwards on picks, and shoot 80+ from the line? He has some liabilities but he could be a very solid rotational player for a championship team like he has been with us these past few years.
