High MinutesWhen evaluating LeBron's impact on his teammates' 3PT shooting abilities, it is most important to consider the % change with him on/off the court. I decided to show both the regular season and the playoffs, since LeBron tends to play heavier minutes in a different style come playoff time.
Low MinutesI also only showed the teammates that shot more than 20 threes per sample since anything smaller than that isn't good data. Any teammates that were excluded from this sheet either didn't get enough minutes or don't shoot threes.
Doing my best to isolate the single variable of LeBron being on and off the court, I labelled any improvements of shooting percentages with green and any regression with red. I decided to leave any data I considered irrelevant or unfair to this argument in white.
It is clear that the left side, when LeBron shares the court with his teammates, is more often green than red. Any cases of improvements with him off the court are small sample sizes, with n<30.
One could easily run a 2 sample t-test to see the liklihood of LeBron having an effect on his teammates shooting, but I feel as if the results speak for themselves and I was told to keep the sheet simple, user-friendly, and I know not everyone understands the gravity of a high t-score.
