Other than last year, most Belichick coached teams have improved as the season went on. I'm hopeful that the Broncos game will be the Pats worst of the season. I expect improvements from the O line as they get healthier. I expect the defensive line and linebackers to improve as the young players get more reps.
With the amount of cap space the Pats will have next year I expect that this will be a competitive year, but the team will really take a big step forward next year with free-agent signings and trades.
