Player X Making Strides In Rehab Program is one of the most well-worn offseason tropes in the game. Especially popular is rehab footage of a player -- typically in recovery from a lower-body malady of some sort -- doing work in the pool. We saw it last month with Cardinals running back David Johnson, who straight-up jumped out of his swimming hole a month after suffering the type of knee injury that would leave you or I on a death bed.
