Drilling in: Offense

QUARTERBACKS: Starter -- Aaron Rodgers. Backups -- Brett Hundley, DeShone Kizer, Tim Boyle.

Rodgers is one of the most gifted passers in league history and currently holds the all-time mark for passer rating (103.8). In Rodgers' last 17 games, he's thrown 43 touchdown passes and just eight interceptions. He has a rocket arm, is extremely accurate, has terrific feet and a brain to match. In two of the past five years, though, Rodgers suffered broken collarbones and missed at least half of the season. Green Bay fell apart both years, going 5-12-1 in the games Rodgers missed (.306). The Packers simply can't afford to have Rodgers out for any length of time if Hundley and Kizer don't progress.

RUNNING BACKS: Starter -- Jamaal Williams. Backups -- Aaron Jones, Ty Montgomery, Devante Mays, Joel Bouagnon.

Jones has been suspended the first two games for violating the NFL Policy and Program for Substances of Abuse. When Jones returns, look for him and Williams - both second year players - to split carries. Last year, Jones was arguably the most explosive running back head coach Mike McCarthy has ever had. Jones averaged a whopping 5.53 yards per carry and had runs of 20 yards or more, on six of his 81 carries (7.41 percent). Williams was kept in mothballs the first half of 2017, then averaged 17.8 carries and 65.3 yards per game over the final eight games without fumbling once. The knock on Williams, though, is he lacks explosiveness. Montgomery was the Packers' preferred starter at running back when 2017 began. But Montgomery couldn't stay healthy, suffered rib and wrist injuries, and was passed by the two rookies.

TIGHT ENDS: Starter -- Jimmy Graham. Backups -- Marcedes Lewis, Lance Kendricks, Emanuel Byrd, Kevin Rader, Ryan Smith.

The Packers signed Graham in free agency, and he has the potential to be Green Bay's best player at that position in years. Graham doesn't run like his early days in New Orleans, but is coming off a 10-touchdown season. The free-agent addition of Lewis should be an enormous positive, too. Green Bay hasn't had a tight end who's been a hammer in the run game since Mark Chmura 20 years ago, but Lewis could fill that extremely important role. Kendricks had a disappointing first year in Green Bay and will compete with the undersized Byrd (6-foot-2, 240) for the No. 3 job.

WIDE RECEIVERS: Starters -- Davante Adams, Randall Cobb. Backups -- Geronimo Allison, J'Mon Moore, Michael Clark, Trevor Davis, DeAngelo Yancey, Marquez Valdes-Scantling, Equanimeous St. Brown, Robert Tonyan Jr., Jake Kumerow.

In the last two years, Adams has 22 touchdowns - the most by any receiver in the NFL. Adams is also the only player in football with at least 70 receptions and 10 touchdowns in each of the last two years. Adams passed former teammate Jordy Nelson as Green Bay's No. 1 receiver early in 2017 and went to the Pro Bowl for the first time last season. The diminutive Cobb is unlikely to ever match his 91-catch, 1,287-yard, 12-touchdown season of 2014. But Cobb has averaged 68 receptions, 697 yards and five touchdowns over the last three years. Green Bay selected Moore in the fourth round of April's draft (pick 133), Valdes-Scantling in the fifth round (174) and St. Brown in the sixth (207). Holdovers Allison, Clark, Davis and Yancey will also battle for roster spots. Allison has 35 catches over the last two seasons, Clark stands 6-foot-6 and has 4.53 speed, Davis has 4.41 speed and Yancey was a fifth-round draft choice in 2017.

OFFENSIVE LINEMEN: Starters -- LT David Bakhtiari, LG Lane Taylor, C Corey Linsley, RG Justin McCray, RT Bryan Bulaga. Backups - T Kyle Murphy, T Jason Spriggs, T Byron Bell, G Cole Madison, G Lucas Patrick, G Kofi Amichia, G Ethan Cooper, C Dillon Day, T Adam Pankey, G Alex Light, C Austin Davis.

The biggest question for this group is if - and when - Bulaga will return. Bulaga is trying to come back from a torn ACL for the second time and isn't expected to be ready until the early part of the season, at best. Bakhtiari is athletic, light on his feet, extremely consistent and has been one of the NFL's top left tackles the last two years. Taylor is a classic overachiever who finds a way to get it done each week. Linsley is extremely bright, quick and earned a three-year, $25.5 million contract extension late last season. McCray played four positions last season and held up well. He's a limited athlete, but has a leg up at right guard after a solid 2017 performance.
