logically, if Shockey knew, Brees knew. If Brees knew, he has no business representing the players
It would be hard to think that Brees or for that fact any other player on the team did not know about it. Of course knowing and participating are very different. As a team leader I think Brees might have stepped up and told his team that this was really not an appropriate thing to be doing. I think he could have got away with it. It sure would be in his best interest because knocking out QB's appears to be a high value target. If one team has such an operation I would think the other team would be quick to retaliate in the same manner so just how many teams are involved? We will never know.
