During the last game of the 2016 season against the Los Angeles Rams, Johnson got twisted up and left the game with a MCL sprain.
That game was on Jan. 1, but by Feb. 8 he was back doing incredible things. Johnson Tweeted a video of himself performing a Pool Box Jump out of thigh-deep water. The exercise requires great explosive power, and the water provides resistance to strengthen his lower-body muscles.
