Broncos: Building a season around a departing halfback
After struggling in 2016, there will only be more question marks on Ben Hunt's role this year after he signed with the Dragons. Can his teammates gel with him, and the fans get behind him, even though he wants to leave the joint?
The Raiders will field one of the best, and most well balanced teams in 2017, but can they trust Edrick Lee in the big games. The lanky winger's shocking performance in their preliminary final loss to the Storm left Raiders fans devastated, and wishing for one more piece to the puzzle.
The premiers will be fielding a similar team to last year, but they will sorely miss the retiring Michael Ennis. Can Daniel Mortimer, Jayden Brailey or Manaia Cherrington replace his leadership and aggression? Probably not.
While the players probably knew it was coming, the Sea Eagles still face a massive challenge to replace the experience and leadership of retiring stars Brett Stewart and Steve Matai. The duo will also likely waste a huge chunk of the 2017 salary cap.
With Billy Slater set to return from injury, Cameron Munster will likely fill the void left by Blake Green at five-eighth. The Storm backline played superbly with Munster at the back last season, but now question marks surround his ball-handling and kicking ability.
It's hard to nail down just one weakness in the Knights' current roster with the team littered with fringe-first graders and youngsters. However their front-row looks especially weak, with Josh Starling the standout player.
After their horror season off the field in 2016, there are huge question marks over the administration of the club this year. While we know the players will show up week after week, how will the all-new board and officials deal with adversity, including Semi's court case in May.
A halves pairing of Te Maire Martin and Nathan Cleary will no doubt be the NRL's least experienced this year. While we know Cleary is an old head on young shoulders, it remains to be seen how this young pair will play alongside each other.
The Rabbitohs possess good big boppers in the middle, and plenty of strike out wide, but on the edges they are certainly lacking. Centres Bryson Goodwin and Hymel Hunt, will team up with Kyle Turner and John Sutton - in partnerships that won't scare opposition defenders.
Unfortunately for the Dragons, their weakest position is also the most important position on the field. While coach Paul McGregor has been talking up the prospects of the experienced Josh McCrone to replace Benji Marshall, youngster Jai Field is also in the running with Kurt Mann and Shaun Nona.
The Roosters have an incredibly well balanced best 17 on paper, so the easy weakness to identify is the incoming Luke Keary who will probably take time to gel with Mitchell Pearce. Keary was in and out of the Rabbitohs starting side last year, and will be hoping the same doesn't happen in 2017, with Connor Watson waiting in the wings.
Warriors: Toughness and passion in the forwards
This Warriors team looks incredible on paper with the inclusion of Kieran Foran. Unfortunately for the Warriors, so often they get outcompeted by inferior sides who just want it more. Can their forward pack step it up under the coaching of Stephen Kearney and start grinding out their opposition.
With so many of their best players currently in contract negotiations there's no doubt much of the team will be distracted. If any of the big names are forced out of the club, the playing group may split.
