We did not have our normal Caption This contest earlier this morning, but after hearing Carlos Rogers discussing how cool it was to have the entire starting defense returning in 2012, I couldn't help but think back to this picture. This is actually the special teams unit, so I suppose it is not quite the same thing, but it's still quite possibly my favorite picture from the 2011 season. The swarming tacklers really defines the aggressive nature of the 49ers special teams and defense.

There were a lot of great pictures from 2011, so if you think you've got something better, drop a link to the picture in the comments. And if you think you can come up with a caption for this bad boy, go to town. It's not really ideal for captions, but we've got some fairly creative folks here at Niners Nation. It's been a quiet Friday, so get those creative juices flowing.
