I predict Leonard will stay with San Antonio and he signs that 219M extension (him and the organization work things out).
That said, Kyler isn't exactly the most reliable reporter out there. I mean, he's certainly knowledgeable about basketball but isn't exactly a guy who gets many rumors right (and not the first guy who breaks big news like a Woj/Shams/Stein).
I still think the extension happens but still no official word yet. This sounds like just pure speculation and a prediction from Kyler to be honest. Otherwise we'd be hearing much more about it as well in the national media/news.
