We definitely need Aldon Smith against explosive offenses. Our pass rush hasn't been good at all since he went to rehab. Yes, we bring some heat when we blitz, but look who we have played. Like someone said earlier, that will not work against the Brees of the world. Locker had a clean pocket for much of the game.
More importantly, hopefully Aldon is a changed man when he returns. One more strike and he may be gone for good.
