‘Cooper brings a legitimate boundary target for Allen. The 30-year-old is averaging 2.7 yards of separation per route run and gives the Bills a threat when teams want to challenge their offense with man coverage. Cooper had 1,250 receiving yards and five touchdowns last season, playing with veteran Joe Flacco for most of the season. Allen is the best quarterback Cooper has ever played with, and he has gone from a 1-5 team to a Super Bowl contender.’
