Impossible to say without knowing what the roster looks like. The first step should should be quarterback, of course. I'll be extremely disappointed if they don't take one in the 1st round, but there are other ways to go behind center, even if I think they're the wrong ways. After that, if they don't think any players are salvageable outside of the obvious ones and take a scythe to the roster, we're probably looking at 6 or fewer wins. If they think they can build on what's here, then we should see 8 or more.
Since they're sticking with the 3-4, my guess is we're not going to see re-building.
Either way, wins or losses aside, success for me will be putting a competitive product on the field and being a better team in week 17 than in week 1. That's really it.
