In “thunder” and lightning speed, Carmelo Anthony is finally gone. One day after Anthony finally opened up his wish list to include the Thunder and the Cavaliers, the Knicks sent their 33-year-old declining star off to Oklahoma City, agreeing on a framework of a deal centered around center Enes Kanter and Doug McDermott, multiple NBA sources confirmed to The Post. An NBA source told The Post the deal will be announced Monday.
