'Harvin, 27, has played in only 28 games in the past four years, while bouncing from the Vikings to the Seahawks to the Jets to the Bills. The player who once was one of the league’s top all-purpose threats caught just 19 passes for 218 yards and one touchdown while knee and hip injuries slowed him in 2015. One thing to remember: 16 of those receptions were in Buffalo’s first three games, and he could be a legitimate No. 2 threat alongside Sammy Watkins if he could continue that kind of production over a whole season.'
