Reddit user Noahsbun has done an incredible job by sorting through LeBron James’ 2014-2015 stats, and then creating a graphic featuring them based on what accessories he was rocking. The accessories involved were simply the headband, his left sleeve, or his right sleeve. When broken down, it shows that LeBron had six different combinations of his accessories and there were fairly large differences in field goal percentage, three point percentage and free throw percentage.
If I were a part of the Cavs upper management I would forbid James to wear just a right sleeve and no headband.
