Naw, Anderson didn't get blown by and he was a good one on one defender. That's why he got signed to a big contract. He's not an elite talent, but he's a good NBA player that can be a starter or a key guy off the bench for a good team. Offensively, yes, he's challenged and that's why no one guards him outside the three point line. If he could shoot 3s at a 40% clip, the Spurs would have gladly matched. He's better than what we have on the roster at SF outside of Kawhi, but his price tag was too high, so now we have what we have. He wasn't going to be the difference between 50 wins or not, but he could make a difference in a series in the playoffs depending on who we play.
Plus, he's still developing. He could be a 40% shooter in two years. Spurs just didn't want to take that risk at his price tag.
