How? Lets just break it down.
Safeties - Same pair, year older. Worse
Corners - Lost 1 starter. Another wont be ready until who knows when after the season starts. Key backup out longer than that. We added a cast off and a rookie who we hope will be ready. Far worse shape than last year.
LB - Worse. Kendricks was about all we had until Overhown flashed. Now hes coming off injury, who knows when. We added two meh's.
DE - Push with a chance to be better. Lawrence will be missed.
DT - Push. But we suck.
Offense a push. Booker doesnt give us much, IMO. Cooks wont be missed. I like Tolbert and think he can be a 2. Mingo and Campbell are unknowns.
QB - Slightly worse. Dak a year older and coming off injury.
RB - Push. Blue isnt Gibbs. Everyone else is meh.
TE - Could be better if Schoon takes a step.
So yeah, this team is worse. Push at best. Every other team in our div is better. So 6 wins it is.
