In 2015, Robert Woods pulled his groin in the preseason and played through the pain all year. He didn’t put up the numbers he had hoped to. Overall it was a disappointing season for him because of the injury.
Percy Harvin, who the Bills were counting on to be their number two, did not play for the team after Week 5 against Tennessee. This offseason, Harvin decided to retire after an injury-plagued carreer. The Bills added a few veterans to their squad towards the end of the last season but the unit overall had no real depth outside of star wideout Sammy Watkins.
