My favorite example of this was a late-game sack against the 49ers this season. Mack was running a basic stunt with Raiders defensive end Justin Tuck, but his refreshing size and speed combination took it to another level. Mack was playing against a solid -- albeit tired and beaten-up -- 49ers line and completely fooled Jonathan Martin into biting on his outside move. This is a believable and very-real threat for Mack on any snap which is why Martin drifted so heavily. He quickly realized, though, that Mack can get upfield better than just about any rush linebacker in the game right now.
