Asik is valuable because he would fill a huge defensive hole and plays the hardest position to find a competent starter for. If we got him and the 7th overall pick this year, we could have:
Rondo
LaVine/Exum
Green
Sullinger
Asik
Which right there is about 2x as good as our team is now and is totally plausible. Then, when you add in the Pierce exception + one of Green or Sullinger and a pick, we could make a move on replacing one of those two for a huge upgrade. So let's say we moved the TE/Sullinger/1st rounder for Melo. Then we would have
Rondo
LaVine/Exum
Green
Carmelo Anthony
Asik
Plus we'd have a bench of Crawford, Bradley, Wallace, Bass, Lee, KO, Vitor and our second 2014 pick. If we didn't get Asik, we'd have to spend all our resources to get someone else who might not even pan out to play the 5, because in order to be truly competitive you need a legit defensive starter at that position. By getting Asik, we could fill out the team around him with above average pieces.
Either one of Larry Sanders or Asik would be a great piece in the middle as a rebounder and rim protector.
They're both beasts around the rim and Sanders in particular has plenty of room for improvement on the offensive end. I also read somewhere that his favorite player is Kevin Garnett because of his heart.
He has called out his team mates for lack of hustle and toughness but only when appropriate IMO.
His ceiling is what's scary to me- he's got an IQ on the defensive end with rotations.
Asik is a smart defender and excellent on ball defender in the paint.
The benefit of Asik as everyone knows is the cap hit of his contract. At only 8 million he is the perfect piece for a contender that wants to save as much money on their tax hit as possible.
Putting Asik in that line up instead of Sander could be the difference in signing a $10 miilion guy (ie Lance Stephenson) or settling for a 6 million guy like Bradley.
I'd prefer to keep Sully On the bench and rotate Green and Sully in our line up as starters next to Melo.
