One league source advised me in Las Vegas to keep an eye on the Knicks and Lakers discussing a potential Westbrook deal if — IF — Leon Rose can successfully bring Donovan Mitchell to Madison Square Garden. The source’s thinking: After adding Mitchell, New York would be expected to explore scenarios to trade away Julius Randle. And Randle, just one season removed from his breakthrough to All-Star and All-NBA status, is presumably the sort of player that the Lakers would have to consider taking on if — IF — they are unable to use Westbrook’s $47.1 million expiring contract in a trade for Kyrie Irving.
