His per 36 steals and blocks numbers have steadily increased since he entered the league. He steals went 1.5, 1.7, 1.8, and 2.1 over the last 4 years. His blocks went 0.7, 0.8, 0.9, and 1.1. There was a clear pattern of improvement on defense, to the point that he was among the leaders in many advanced defensive stat categories last year. Maybe the 2.1 steals and 1.1 blocks were an outlier, but they didn't just come from out of nowhere. There was a steady progression, and it's been shown that most players actually put up better per 36 numbers when given more minutes (up to a certain point). But if he's really only capable of 1.8/0.9 stocks per 36, then it will be very difficult for him to be fantasy relevant. That jump to 2.1/1.1 was basically the sole reason that his per 36 value skyrocketed last season (going from outside the top 170 to number 77 in my settings). Very little else changed over the two years prior. Honestly the other thing that worries me about Anderson is his lack of involvement on offense. I didn't see last game, but almost nothing is ever run through him as a playmaker. He needs to put up around 8 points and 3 assists to match last year, and right now he's looking more like 6 and 2.
