Chances are both injuries didn't happen in the same game. That's the side I'm taking
We know both injuries didn't happen in the same game.
Here's a fun little game to play though.
Did Aldon Smith's responsibilities change with the injury to Justin Smith? Was he asked to do more in terms of defending the run?
Why do you present this as if Aldon Smith would have 0 sacks on the season if Justin Smith didn't play at all?
