Jacksonville's revamped secondary, which includes rookie cornerback Jalen Ramsey and two more newcomers, faces arguably the toughest test possible in the season opener.
Ramsey, cornerback Prince Amukamara and safety Tashaun Gipson should find out where they're at, and maybe where they need to be, when the Jaguars host the Green Packers on Sunday.
With quarterback Aaron Rodgers and receivers Jordy Nelson and Randall Cobb, the Packers have one of the league's most potent passing attacks. Even without Nelson, Green Bay's biggest deep threat who missed all of last season with a knee injury, the Packers ranked second in the league with 39 passing plays of 25 yards or more. They have 117 of those since the start of the 2013 season, trailing only Pittsburgh (118) for the most in the NFL.
Thanks to the Pack coming to EverBank Field, the Jaguars have their first home sellout since playing Pittsburgh in 2014.
