Every NFL team has a weakest link—some just take longer to show than others.
For a few franchises, the flaw is immediately apparent, like when Eli Manning caused the New York Giants to drag their feet last season. Sometimes it doesn't show until midseason, like when the Cleveland Browns made a stunning turnaround after they fired Hue Jackson.
And sometimes the weakest link stings at the worst moment, such as during the Super Bowl when the Los Angeles Rams' pass rush couldn't get to Tom Brady.
Regardless of when a problem reared its head, NFL teams are ready for the free-agency gates to swing open March 13.
