If you’re talking about defensive stars who will be relied upon the most, the answer is Shaq Barrett.
Drew Brees is going to find holes in the coverage. That’s simply what he does. But you can’t give him all day back there to throw the ball.
For the Bucs to have any type of success slowing down that Saints offense, you’ve got to see Barrett in the backfield providing pressure. He’s going to be relied upon to do it all in this game specifically and will be a huge detriment or asset to the team’s success.
