Paul Richardson only played in one game in 2015 while coming back from a torn ACL. He started the season on the PUP list, debuted in Week 10, but pulled his hamstring making a long catch down the sideline (a common injury for players recovering from knee injury as the body often compensates for injuries like that).
Two injury-shortened seasons don't seem to have sapped Richardson's resolve though, and from the video posted to his instagram below, looks like he's in good shape to start next season off fully healthy.
With Jermaine Kearse potentially leaving in free agency, Richardson will have a good shot at seizing some major playing time in 2016 next to Doug Baldwin and Tyler Lockett.
