On Wednesday, the Green Bay Packers promoted third-year quarterback Graham Harrell to the active roster. Why is this relevant here? Why, because it was interest from the Buffalo Bills that prompted the Packers to give Harrell said promotion.
Per the report (which was relayed by Chris Brown, Harrell was courted by the Bills to become their third quarterback. As a member of Green Bay's practice squad, Buffalo could only pursue him as a member of the active roster - and in doing so, the Packers would have an opportunity to block his move by offering him a spot on their own active roster. Harrell got those offers from both teams and decided to stay in Green Bay, where he has an excellent shot of becoming Aaron Rodgers' primary backup next season.
This is interesting from the Bills' perspective for two reasons. First and foremost, it indicates a desire for the team to be developing a quarterback prospect long-term; the 26-year-old Harrell would have fit that description. I'm also curious as to how Brad Smith's move to wide receiver affected this move; the Bills have really only had two quarterbacks all season, but now their emergency option is needed elsewhere. If the decision to court Harrell was based solely on numbers, that would be a decidedly less interesting maneuver.
Either way, the Bills appear to be on the lookout for a quarterback.
