Note: NFL.com updated its list after several teams made franchise/transition tag designations and other roster moves, which caused some changes in the rankings.
Now we're starting to get serious. The free agents who fall into the 20-39 range are considered to be in the upper tier of players in the NFL, guys who can inject some major talent to another roster.
There's a defensive flavor here as 12 of the 20 players are defensive stars. A handful of players have also played for Vikings Head Coach Mike Zimmer, something to keep your eye on as free agency gets underway on Wednesday.
