The minimum salary in the NFL is decided by how many years the player has played in the league.
For the 2010 season, the minimum salary for rookies was $320,000. One year players minimum was $395,000, two year players minimum was $470,000, and three year players minimum was $545,000.
For players that had 4-6 years in the league the minimum was $630,000. For players with 7-9 years in the league the minimum was $755,000 and for those players with 10 or more years the minimum was $855,000.
I think George Blanda is likely the player with the longest career.
A player can be franchised a maximum of three times in a row.
