If this was actually being entertained.... The price proposed is too low and, the actual price in acquiring JA now, in his prime, one of the most dynamic and talented players in NFL history, would legitimately cripple a franchise like the Bears. It wouldn't be worth it.
Now, a team like the Niners, theoretically could offer the moon to win a SB or two but again, so much draft capital would need to be expended to make this happen...it's just not realistic.
