Steph Curry and Regression to the Mean

After Game 2 and 3 of the Golden State-Memphis series, in which Steph Curry shot a 2 of 11 and 2 of 10 respectively, there was talk about whether Memphis had figured out Curry. There was talk about whether a jump shooting team could win a title relying on outside shooting.

Or was this a case of regression to the mean? This means that after a small sample size that is far from average, future samples will go back to historical averages. In taking a look at Steph Curry’s 3-point numbers this season, we can see a fluctuation around his average percentage of 44.3 percent.  There is clearly a lot of variance in individual game numbers.
