The New Orleans Saints seem to have improved their roster thus far in free agency, but it's always important to remember these changes don't happen in a vacuum.
All 32 teams in the NFL try to use free agency as a way to help their team, whether by adding players or creating salary cap space for future use.
The most important teams for the Saints to evaluate are the ones in their division, the NFC South, and the Atlanta Falcons, Carolina Panthers and Tampa Bay Buccaneers all made some moves over the past 11 days to improve their teams -- dating back to the open of the NFL's negotiating window two days before the 2017 league year began last Thursday.
