Closer look at 49ers' field-position gains

Nater from Iowa City asked about the San Francisco 49ers' high rankings in field position this season. He wondered how much of it had to do with punter Andy Lee, the team's turnover avoidance, etc.

Mike Sando: The 49ers have helped their field position in many ways this season. Football Outsiders tracks field position across a long list of categories. I went through the 49ers' rankings from 2010 and 2011 and put together a chart showing the gains they've made in the "net" rankings listed at the bottom of those above-linked pages. These are striking gains.
