The former first-round pick of the Browns was acquired by the Bills for an undisclosed future draft pick.
Before Corey Coleman arrives at St. John Fisher, he must pass a physical in Buffalo to complete the trade with Cleveland.
Coleman has been a bust with the Browns, who selected him with the No. 15 overall pick in 2016 - the first selection by Cleveland's previous, analytics-driven front office.
Coleman's tenure with the Browns will be best remembered for his drop late in the fourth quarter in last season's finale at Pittsburgh that sealed the Browns' 0-16 finish. "I'm sure he wished he had played all 16 games both seasons", Beane said.
"We'll tell him how we do things here, what the expectations are. You can turn on the clips, he makes a lot of good plays", he added.More news: Two elderly men escape nursing home, found at heavy metal festival
Now Coleman will need to take that step with the Bills, where he will need to get acclimated to Buffalo's offense in short order.
Coleman also had off-field issues.
The Bills made a significant move concerning their wide receiving corps Sunday. They also have used Jeremy Kerley as a slot receiver. In his first two seasons, Coleman tallied 56 catches for 718 yards and five touchdowns. "He's just coming in here to compete and earn".
Buffalo sent quarterback Tyrod Taylor to the Browns in exchange for a third-round pick this offseason.
By trading the No. 2 pick to the Philadelphia Eagles, the Browns passed on the chance to select Carson Wentz, a 6-foot-6, 235-pound quarterback whom chief strategy officer Paul DePodesta felt that despite being a two-year starter for National Championship teams at North Dakota State, did not have the potential to be a top-20 NFL quarterback.
