The Rubio logic is valid...chemistry DOES matter. But talent does too. In Ricky's case, he isnt so overwhelmingly great on defense that his horrible shooting can be overcome, especially given the other non-shooter the Jazz have in Gobert. As for Irving, he wants to be "the man." That's why he no longer wanted to play alongside Lebron. Jazz already have their alpha in Mitchell. I dont see how those two could co-exist. Jazz need another scorer, not a ball dominant PG.
