Klay isnt going anywhere, if he is, they would have traded him for Kevin Love already.
That contract dispute is just a power play by his side to secure a max contract. Klay is RFA and the Dubs have all the leverage. If he gets a max offer sheet, they can easily just match it. If he doesnt, then Dubs doesnt have to pay max.
His camp is just pushing for the max so he gets paid, regardless of performance. Sorry, not going to happen...
