Thought it was a pretty terrible article. KA's been bad, but I don't think they expect him to have impact this season. The fact Pop has him on a short leash is a positive, not a negative, for his case. They'll be picking his options and expect more of him in his 3rd and 4th years, just like with CoJo. He's just been given a chance to earn the 4th wing spot, which seems like a huge problem for the Spurs right now and isn't doing too well admittedly.
If neither wing steps up the Spurs would have to look for a veteran to trade for at the deadline. Pop can run a 3 man bigs rotation come playoff time, but it'd be difficult to run a 3 wing one as well, especially when some small ball is expected too.
