Time 1, 2, 3, and 4 correspond to preseason in Season 1, postseason in Season 1, preseason in Season 2, and postseason in Season 2, respectively.
Within‐group difference was tested using Wilcoxon signed rank test. W and W 0 represent W value and critical W value, respectively.
Between‐group comparison was tested using Mann–Whitney U test. U and U 0 represent U value and critical U value, respectively.
