Precisely.
And that is why I say coverage is slightly more important than pressure in today's NFL. Guys have to be able to cover no matter what the situation, pressure or not. Brees looked flustered, as his receivers weren't getting open. He was forcing the issue all game. And even on his TD pass to Stills was a low percentage throw.
The defensive gameplan can only work when you have guys that can execute it. People wondered why the scheme was so vanilla in past years, it was because they lacked the proper personnel to pull it off consistently.
When you have a guy like Talib playing at high level like he is, basically making the game 10-on-10, your chances on defense increase greatly. That's been the key. Aqib is playing the best at the CB position in the NFL. Unlike Sherman, who stays on one side of the field, Talib is assigned to a guy wherever he goes and shuts them down all of 'em.
