I think we are undervaluing the talent of Mack somewhat. The first player ever to be named All Pro at two different positions? And he's just in his prime as a player? He's a rare, transcendent player; the guy an offense has to account for before EVERY snap. We don't have anyone like that on our defense. As such, I think the minimum price will be what we paid for Biscuit back in the day and, imo, he's worth it seven ways to Sunday. Polian's formula still stands today; if you think you have your QB, then you get a player who can get to the opponent's QB.
