I am gonna go with unabashed homerism and say 8 wins. I think that's very possible if: the potential at WR mostly pans out, the oline continues it's progression and really does take a step forward, the RB room solidifies itself, and the D doesn't step back from last year. Oh yeah, and as HWM said, AM has to stay healthy. I know that sounds like a lot to happen, but honestly all of those things should or at least quite possibly could happen.
Until I see us ay an egg against a team being coached by a new guy in their first game I'm gonna stick with it.
