Chronological Timeline
4 Recorded Trades
Trade 1 of 4
Buffalo Bills and Las Vegas Raiders
Buffalo sent linebacker Bill Laskey to Oakland for a 1967 sixth-round pick that became No. 149, Bill Wilkerson. Laskey became part of the Raiders' linebacker group, while Buffalo chose future draft value instead of retaining him. With the separate Dave Costa transaction removed from this record, the direct player-for-pick comparison gives Oakland the clearer football return.
