While i do agree, I think the biggest reason it came together was Chychruns fall down the lineup. Arizona wanted him, and finally decided to pay the price.
It would of happened either way , if it wasn't chychrun they would of found someone else they liked to make that deal .... If they wanted to they could of done the 20th and 2nd rounder for 16th
Adding datsyuk was not only a bonus for us but for them ... Trust me next year they'll be chasing other cheap contracts when datsyuks and prongers deals are done
