There's been a lot of talk about if Aaron Rodgers will be back or not (personally, I think this is the best article on the whole situation, but maybe I'm biased).
With the uncertainty at quarterback, the wide receiver corps has been a big topic. Everything from Davante Adams's contract to the drafting of Amari Rodgers to the return of Devin Funchess. It's possible this talented group could make things a lot easier on whoever starts for the Packers this year.
The running game has also received a lot of attention, where Aaron Jones and AJ Dillon could be a top tandem in the league.
