I think it depends on how we do "Out of the gate". If we have a poor showing with more losses than wins pre-bye week, then I see sub .500 a true possibility unfortunately and I think it boils down to our defence, show up week one and do what they do best and we're off to a winning season.
With my homer blinkers off I see it like this:
1. We have one of the, if not THE best
D-lines currently playing, they just seem to start slow, bring it guys, every week - please!
2. Our
secondary dept. is maturing well, with flashes of brilliance now and then - I hope the errors are minimised this year.
3.
Special teams & trickery, on our day, I don't think there's a better set of STers in the league
4.
Greg the Leg needs to reduce his wayward kicking, I really don't want missed PATs this year of fluffed sub 40 FGs
5.
QB: we've got a good starter, but he needs to improve on last year, I hope he stays healthy throughout the season (
and post-season)
6.
WRs: since adding Britt last year, I think we have a great set of WRs, not a Holt or a Bruce, but solid, and a bit of depth too - hoping Britt brings it again this year and Quick can return to the form we saw last year, Austin and Bailey could be threats in this league, I'm hoping Cignetti can use them to their potential.
7.
RBs: Please don't rush Gurley back on the field, Mason is a more than capable starter and he's going to want to show the FO that he has the tools and ability to be a starter and lead-back in the NFL, he will also want to show other teams how good he is

8.
O-line: ohh our much maligned offensive line... there are whole-sale changes here, they're young, they're big and I'm excited!!!
9.
Coaching: Consistency please, Fisher can out-coach one week, but his game-plan can get torn apart others, we go from looking like contenders to one of the worst teams in the NFL, I just don't get it!
10.
Penalties: Just cut 'em out guys, wouldn't mind seeing how many points we lost due to penalties last year...
With the OC, O-line and QB being totally new, it's difficult to project where we'll fall this year it could be 6-10, but the potential is there for a 12-4 season too, it's all about the pre-bye week for me, if we go 5-1, then we're on - but I do worry about what happens if we go 1-5, both seem like possible outcomes!
