What happened: Trade speculation surrounding Marvin Harrison Jr. centers on the Buffalo Bills due to staff familiarity. Buffalo receivers coach Drew Terrell spent the previous three seasons evaluating the wideout as the Arizona Cardinals pass game coordinator. Bills assistant head coach Jeff Rodgers also spent seven years on the Arizona staff.

Why it matters: These coaching connections give Buffalo direct insight into the receiver if the front office explores an acquisition. There is currently no indication that the Bills have initiated formal trade discussions.

What to watch: The front office will determine if their internal evaluations justify a formal trade offer.
