For cornerbacks coming back from injuries like Dominique Rodgers-Cromartie, recovering mentally is just as important as returning physically.
All three are coming off injury-affected seasons. How well they recover -- physically and psychologically -- qualifies as an important storyline for each of their teams this summer. Cornerbacks without confidence quickly become liabilities. How well these corners compete in training camp could prove pivotal.
Some of the signature moments and games in the NFC West last season came at the expense of division teams' pass defense:
Johnson surpassing 190 yards receiving against the Seahawks and one week later against the St. Louis Rams.
The Green Bay Packers' Aaron Rodgers passing for 423 yards and four touchdowns against the Arizona Cardinals in the wild-card round, narrowly missing a wide-open Greg Jennings for what could have been an 80-yard touchdown strike in overtime.
The Seahawks, 49ers and Cardinals need their top cornerbacks at their best to compete effectively in an increasingly pass-happy NFL.
