The two teams getting the most speculation during the NFL preseason, the New England Patriots and New York Jets, are garnering that attention for different reasons.

Some think the Patriots will go undefeated during the regular season, as they did in 2007. The oddsmakers in Las Vegas have high expectations for New England, too – the lines released by sports book operator CG Technology in May had the Patriots favored in every game. The Jets, on the other hand, have been cited by one unnamed NFL executive as having “the worst roster I’ve seen in a decade.”

Either of these extremes is a rare occurrence. The 2007 Patriots are the only team in league history to finish the regular season 16-0, joining the 1972 Miami Dolphins (14-0) as the only other team to go undefeated since the NFL-AFL merger of 1970. Only four teams have gone winless for an entire season since 1944: the 1960 Cowboys (0-11-1), the 1976 Buccaneers (0-14), the 1982 Colts (0-8-1), and the 2008 Lions (0-16).

The optimism for the Patriots is easy to defend. They went 14-2 last season en route to a Super Bowl victory, and based on 10,000 simulated seasons using Football Outsiders’ early season projected win totals, the Week 15 matchup on the road against the Pittsburgh Steelers is the most likely loss for the Patriots (48.2 percent chance), followed by a Week 10 game with Denver (44 percent chance of a Broncos win).

The Jets may find it difficult to win games. A season-ending neck injury to receiver Quincy Enunwa and a broken foot for Lucky Whitehead leaves the team with second-year pros Charone Peake (19 catches for 186 yards in 2016) and Robby Anderson (42 catches, 587 yards, two touchdowns) at the top of the depth chart. The offensive line ranks 20th at Pro Football Focus after left tackle Ryan Clady retired and center Nick Mangold was released.

Yet going winless is still a stretch, with good chances to beat the Cleveland Browns on the road in Week 5 (60.3 percent) and Jacksonville Jaguars at home in Week 4 (52.4 percent). It takes just one win to keep the Jets from making history.

Overall, the Patriots have a 1.1 percent chance (90-to-1) of going 16-0, and the Jets are less than half as likely to go 0-16 (0.4 percent, or 260-to-1).

SAINTS: Coach Sean Payton says cornerback Delvin Breaux needs lower-leg surgery that will sideline him about six weeks and that an initial misdiagnosis of the injury sparked a shake-up in the team’s medical staff.

Payton says Breaux has a fibula fracture that was initially diagnosed as a contusion. Breaux has missed more than a week of practice and Payton said he had been getting frustrated with the pace of Breaux’s recovery, based on the initial diagnosis.

The coach said the Saints will replace two orthopedic surgeons, and in the meantime receive help from Chargers physicians during joint practices in California leading up to their game Sunday in Los Angeles.

COWBOYS: Running back Ezekiel Elliott’s appeal of a six-game suspension over a domestic violence case will be heard by arbitrator Harold Henderson, who reduced Greg Hardy’s ban when the defensive end was with the Cowboys two years ago.

TV: Beth will become the first woman to call NFL play-by-play for CBS – Browns vs. Colts on Sept. 24.
