As we near the midway point of the 2013 regular season, it's time for our weekly look at our alternative to red zone data: opportunity-adjusted touchdowns (OTD).

If you're new to the stat, be sure to check out our introduction to rushing and receiving OTD. The OTD metric weighs every carry/target and converts the data into one number that indicates a player's scoring opportunity.

With seven weeks in the books, the cream is clearly rising to the top. Marshawn Lynch and Calvin Johnson pace the field in their respective OTD categories.
