Mack, 35 and a former Bear, is on an expiring contract that Chicago currently has enough cap space to absorb. Jones pegs Mack’s trade value as worthy of a fifth-round pick, which the Bears also have. The hold up at the moment is that the 0-4 Chargers aren’t ready to deal. Los Angeles takes on the Broncos this weekend looking to avoid going 0-5, but if they don’t it could accelerate their willingness to start trading.
