Running backs, defensive backs and defensive linemen could be popular when free agency begins in March.
The top players scheduled to become free agents are likely to be heavily considered for the franchise tag this month, including Ravens quarterback Lamar Jackson, before shopping can officially begin at 11:59:59 p.m. ET on March 15.
Teams face a March 7 deadline for the franchise tag.
Speculative free agents, such as players with looming contract negotiations that could lead to their release or a trade -- Raiders quarterback Derek Carr or Titans offensive tackle Taylor Lewan -- are not included.
