1. Trubisky's development - The team's long-term success hinges on his development. If Trubisky can be what the team envisions, then regardless of the other set backs, there's always a chance to be successful. If he regresses or doesn't come close to expectations, then the team's only good for as long as the D is intact, which is a scary though. Also, this season is a big step for his development. Will he take the next step or shit the bed?
2. Kickers - obviously
3. OL - no tackle depth. If Leno or Massie gets hurt, we're fucked. I'm okay with the interior though, there's good depth there.
4. TE - Burton disappeared for a bunch of games last season. No real depth after Burton and Shaheen is a bust/unknown at this point. No one else really stepped up in the group when Burton wasn't playing.
5. RB - will the group mesh? I'm excited to see how they do. Cohen will continue to be an electrifying player, but how will the other guys step up. If the run game is solid, it'd take a lot of pressure off of Mitch as well.
6. Growth in Nagy - there were some questionable decisions and playcalling at times this year. I'm hoping to see him improve on things like time management, TOs, and all that jazz. It got a bit infuriating at times seeing the team burn a time out like 10 mins into a game.
7. Potential regression in D - don't think it'll happen but it's always something in the back of your mind on whether or not things will keep as good as they were. Turnovers can be fickle year-to-year but I'm excited to see how they do and how it'll look under Pagano.
8. Injuries - got pretty lucky last year. Though it makes up for being so unlucky the previous 3 years, but these things are so unpredictable that one injury can make or break your season. Just gotta keep our fingers crossed and hope for no major problems here.
