'Last season, Butler, who stands 6-feet-3-inches tall, spent time with the Tampa Bay Buccaneers and New York Jets before latching on with the Chargers. In signing Butler, who turns 26 in April, the Bills now have six wide receivers on the depth chart. They lost Robert Woods and Marquise Goodwin in free agency and are left with Sammy Watkins, Dezmin Lewis, Kolby Listenbee, Walt Powell and newly signed Philly Brown along with Butler.'
