Following up an earlier item, I've put together charts showing where NFL quarterbacks rate when throwing against eight-man boxes and loaded boxes (those where potential rushers outnumber blockers).
The first chart ranks the 12 quarterbacks with at least 20 attempts throwing against eight-man boxes. Most of these quarterbacks play for teams with top running backs.
Thanks to Allison Loucks of ESPN Stats & Information for providing the numbers.

The second chart shows where quarterbacks rate against loaded boxes (more potential rushers than blockers).
