A QB away from what? Making playoffs? I don't think making the post-season would be all that great of an achievement when what this team really wants is to contend for a title more then that. I think the standards aren't that high to make it given who has been making it the past couple of seasons.
I don't think we are a QB away from anything. What position on this team can the unit really hang their hat on? Offense? You don't have a run game, your OL is solid, your WRs are solid but look better compared to the atrocity you had last year and your defense itself has issues that are unraviling. We all thought the secondary would be a supreme strength of the team but Jimmy isn't the player who is he fully capable of being, Carr is solid but not elite, and Marlon is the only guy you hope to have out there but he's missed a couple of games and isn't 100%. There's no pass rusher that you can trust to get a sack when it matters most and this DL is not as good as we hoped because they're getting worked. No coverage in the middle of the field from the LB and while Mosley is good he has a few of his downfalls as well. TJ and Weddle as a duo has been a disappointment and the run game has issues at the 2nd level. Special Teams isn't even good atm.
I don't think there's one place this team can identify as a strength right now. They're just good, solid or average at most places. Every team that wants to contend for a title does something that a very select few can do themselves.
