FOXBOROUGH Adrian Clayborn Jersey Salute to Service , the Patriots defense didn’t become clear until late in the year.Both times the group had stumbles early, followed by steady improvement. Those leaps were aided at least in part by the increased contributions of newcomers or role players that previously had much smaller roles.That pattern is holding true in 2018 as the Patriots prepare for back-to-back road games at Miami and Pittsburgh that will go a long way in determining their playoff seeding.Earlier this season, New England’s opponents took advantage of a defense that struggled to get pressure up front and that was susceptible to giving up big plays in the secondary.After allowing 300 or more passing yards four times in its first seven games, New England (9-3) has not allowed a 300-yard passer in five straight games. It also has not allowed a 100-yard rusher in nine straight games, going back to Week 3 against the Lions when Kerryon Johnson did it.Those are important markers for a Patriots defense that has had trouble recently at Miami. New England is 17-7 against the Dolphins since 2007, but has lost four of its past five at Hard Rock Stadium.Ryan Tannehill threw for 350 yards and two TDs in the Dolphins’ 20-10 win in the 2015 regular-season finale in Miami.That came a season after Knowshon Moreno rushed for 134 yards and a touchdown in Miami’s 33-20 win to open the 2014 season. Tannehill had two touchdown passes in that game to help the Dolphins outscore the Patriots 23-0 in the second half.“It’s a week-to-week challenge in the season,” Patriots Bill Belichick said of his defense’s evolving identity. “We haven’t established anything against Miami, so we’ll have to go down and do that on Sunday and we’ll see what happens. Certainly Kenny Britt Jersey Salute to Service , they’ll be a big challenge for us.”Since allowing a season-high 40 points in their win over Kansas City in Week 6, only two teams have scored more than 17 against the Patriots over the past six games — Chicago (38-31 win over the Bears) and Tennessee (34-10 loss to the Titans).One reason the Patriots defense has tightened has been the improvement of the secondary. That has included key contributions from rookie cornerback J.C. Jackson, who has seen an increased role since Eric Rowe was placed on injured reserve at the end of October.Jackson has two interceptions and contributed to another in last week’s win over Minnesota, tipping Kirk Cousins’ pass into the hands of teammate Duron Harmon in the closing minutes.Linebackers coach Brian Flores, who is calling plays for the defense this season, said Jackson and fellow rookies Keion Crossen and Duke Dawson have earned the trust of their teammates through their work ethic off the field.Belichick said Jackson’s ball skills first caught their attention as an undrafted player in the spring.“He’s just been very dependable and gotten better every day. It’s not always perfect, but he learns from his mistakes and corrects things,” Belichick said. “It’s taken a little time for him to gain some experience, but he’s doing a good job with it.”Safety Devin McCourty said Jackson’s willingness to be on an island at times will serve him and the team well going forward.“I think we’re starting to feel it that he knows we believe in him Authentic Cordarrelle Patterson Jersey ,” McCourty said.“We know he’s talented and can play and we’ve got his back. … We had him in some tough situations where we were counting on him to make plays sometimes by himself with no help and he showed up. He had been doing that every time we gave him an opportunity to be out there.”Week 2 Patriots vs Jaguars: Marcus Cannon needs “impressive improvement” to play tomorrow The New England Patriots will face one of the best defenses in the NFL tomorrow. However, the team’s offense enters its game against the Jacksonville Jaguars with some personnel questions: running backs Rex Burkhead (concussion) and Sony Michel (knee) were both limited all week in practice and appear to be game-time decisions heading into the rematch of last year’s AFC Championship Game.Furthermore, there is a realistic chance that starting right tackle Marcus Cannon misses the contest (via The Atheltic’s Jeff Howe):Cannon did not play when the Patriots met the Jaguars in January due to a season-ending ankle issue, and it looks as if his latest ailment – a calf injury – could keep him out of Sunday’s game as well. Without their the 30-year old, New England would turn to primary backup LaAdrian Waddle to go against Jacksonville’s talented defensive linemen like Dante Fowler Jr. and Yannick Ngakoue.Waddle brings plenty of experience to the table but is a downgrade from the starter he could replace tomorrow: last week against the Houston Texans and All-Pro defender J.J. Watt, Cannon held his ground while playing 61% of offensive snaps. Waddle, meanwhile, was more inconsistent during the 39% of snaps he was on the field for. It would therefore not be a surprise to see the Patriots try to help Waddle with an additional blocker – think tight end Dwayne Allen – at times tomorrow.
