It all depends on whether this team can stay healthy (specifically the O-line). There's better coaching this year, BUT this team just doesn't have depth.
And you can make an argument there for not constructing your team such that virtually all of its strengths lie in the offensive and defensive lines. There is likely relatively weak depth there league-wide, and so if you happen to have injury there, and virtually all of your team strengths are in those areas, there goes your team.
If your team strengths, rather, are spread throughout various areas, you can sustain injury in one or two of them and still remain fairly strong via your talent elsewhere.
Again, so much of success in the NFL rides on whether a team has a strong quarterback. Those players are protected from injury by the league rules, and strong quarterback play overcomes injury elsewhere better than strong play anywhere else does.
