Plenty can change between now and the start of free agency on March 13. But an early picture has started to emerge as to free-agent areas that are deeper than others.
Previously, we shared Pete Prisco's ranking of top 50 free agents on CBSSports.com, as well as Vinnie Iyer's ranking of top 100 free agents on SportingNews.com.
Today, the NFL Network team passes along its notable free agents by position.
Three Patriots defensive ends are on the NFL Network list -- Mark Anderson, Andre Carter and Shaun Ellis. All had signed one-year contracts with the team prior to the 2011 season.
The receiver group looks particularly deep, although that can change between contract extensions and franchise tags.
