IMHO not very...
Maybe we'd make the playoffs, then get swept in the first round. That would likely be the best case.
Problem here is two-fold:
1) I don't think that Love is the type of guy who can be a #1 option on a contender. IMHO he is the perfect example of a guy who gets a lot of points because he takes a ton of shots, because he is the best scorer on a bad team. Love has a pretty limited inside game and too many of his points come off low percentage jump shots - a 46% FG% is poor for a PF or C in this league. Plus he is still a liability on defense. If you want to build a contender with Kevin Love on it, then I really think he's got to be your sidekick, not your superhero.
2) Omer Asik is just plain bad. He would not help this team in any way whatsoever. I would rather just bring Colton Iverson back in from Europe, give him his minimum contract, and let him come off the bench. He'll give you the same type of size and physicality that you would get from Asik, he won't give up much, if anything, on offense (since Asik absolutely sucks offensively) and he'll probably give you better shotblocking...all while saving you about $14 million. He might give up a little bit to Asik on the boards, but probably not that much as Iverson has been an exceptionally good rebounder at the college level and this aspect usually translates well in to the NBA.
I'm going to go out on a limb and say that Omer Asik is probably THE worst contact in the entire NBA. I think he is even worse than Gerald Wallace. If he isn't worse then he's definatley right up there.
You're talking about a guy who is completely unwilling to come off the bench (see current situation in Houston) and yet is nowhere near good enough to start.
So does a trade like this improve the team? Sure. The addition of Asik does nothing to improve us at all. He may even make us worse, because we'd probably have to give up some solid players either by trade of via free agency (Sully, Bradley, Green, etc) to get him. But we'll probably win a few extra games by adding Love. Would we contend though? Hell no, not even close. We'd be most likely knocked out in the first round. Could be even worse, maybe we would just miss the playoffs.
Plus adding those two guys would also throw about an extra $25M - $30M onto our salary cap which would completely kill our cap flexibility for the future.
So at the end of the day would this be a good deal for us? IMHO no, not at all. I think it would be a very poor decision to make this type of move.
