I have downloaded stats for the recently completed 2013 NFL regular season from yahoo.com, cleaned the data, and saved in Excel format. The files are located here. The column headers should be self-explanatory.
There are seven worksheets:
- QB: quarterback data.
- RB: running backs.
- WR: wide receivers.
- TE: tight ends.
- K: kickers. For the yardage columns, the portion before the dash indicates FG made, the portion after attempted. So 4-5 means 4 made out of 5 from the distance range.
- DEF: defensive stats by team.
- ST: special teams stats by team.
The same folder also contains CSV files broken out for each position.

Do you, or do you know where it might be available to get week to week stats in Excel, csv, or a professional pdf form that can be converted to Excel?
This is great; how would one go about doing this for 2014 on yahoo?
