Preseason winding down, difficult to tell what is meaningful or not

The third weekend of the NFL’s preseason, widely considered the dress rehearsal stage for many teams – though quite a few continued to rest star players – is complete. Here’s what we learned:

1. It might be time to worry in Atlanta, Dallas, Miami, Philadelphia, Seattle and Tennessee. Those clubs are winless, and no NFL team has ever finished 0-4 in preseason and gone on to win the Super Bowl since the league implemented the 16-game regular-season schedule in 1978.

2. Interesting (worthless?) stat of the day: San Francisco QB Jimmy Garoppolo is 7-0 as a starter in the regular season but just 4-4 in preseason.

3. Um, the Cowboys have depth issues.

4. There continues to be plenty of buzz around new Chiefs QB Patrick Mahomes. But Kansas City’s first-string offense played into the third quarter Saturday and only scored 10 points against the Bears, who rested most of their starters.

5. Steelers RB James Conner caught six passes Saturday after snaring zero in his rookie season. Further evidence Pittsburgh might be able to survive without no-show Le’Veon Bell?

6. Raiders RB Chris Warren, son of former Seahawks star RB Chris Warren, leads the NFL with 250 preseason rushing yards. The younger Warren wasn’t drafted but is making a case for a roster spot behind Marshawn Lynch and Doug Martin.

7. Philadelphia’s first-team offense has zero points in 10 drives this preseason, though it’s been missing starters like LT Jason Peters, WR Alshon Jeffery ... and QB Carson Wentz.

8. Eagles QB Nick Foles threw two INTs in one half Thursday. He threw three in six starts (including the playoffs) during last season’s Super Bowl run.

9. Second-year Browns DE Myles Garrett seems ready to emerge as a legit defensive player of the year candidate. His sack of Foles for a safety gave Cleveland’s defense two points. (The Browns offense managed just three.)

10. Bills rookie QB Josh Allen got his first preseason start Sunday. Buffalo didn’t score in his half of action, largely because Allen was running for his life behind suspect blocking. It seems like a disservice to start the highest-drafted passer (7th overall) in franchise history in Week 1 given Allen’s lack of big-game experience and a weak supporting cast that would likely force him to try and overcompensate.

11. Adam Humphries’ 109-yard “kick six” – the Bucs receiver brought a missed 62-yard field goal by Lions K Matt Prater all the way back – has been the play of the preseason so far. (But why wouldn’t Tampa Bay keep that play in their regular-season bag of tricks?)

12. The preseason’s best moment occurred Sunday, when Bills fans gave Bengals QB Andy Dalton a standing ovation eight months after he engineered an upset in Baltimore that vaulted Buffalo into the playoffs for the first time this century.

13. NBC’s new “green zone” feature (which shows how long teams have to go on third downs to get a first down) had many fans seeing red.

14. Adrian Peterson, 33, needed just three practices and one preseason game (56 yards on 11 carries) to put a virtual lock on the Redskins’ starting running back job. Washed up? Pfft.

15. QB Josh McCown, who started 13 games for the Jets in 2017, threw one pass this preseason. He was going to have to get used to watching Sam Darnold sooner or later. (Rams QB Jared Goff hasn’t taken a snap this month... so, that tells you even more about preseason.)

16. Packers QB Aaron Rodgers didn’t play this week but threw pregame passes to former teammate Jordy Nelson in Oakland. Meanwhile, Raiders QB Derek Carr threw to Green Bay WR Davante Adams, a teammate of Carr’s at Fresno State.

17. Coach Mike McCarthy held out Rodgers and several other key starters because he didn’t want them playing on Oakland’s infield baseball dirt, according to former Packers WR (turned NFL Network analyst) James Jones.

18. Elsewhere, the Saints scored 36 points on the Chargers’ soccer field.

19. Giants WR Odell Beckham Jr. still hasn’t played in a game since breaking his ankle last season.

20. Slide, Cam... it’s preseason. The Panthers QB wound up with a shiner after failing to “bring this plane in as smoothly as possible” while diving for a first down.

21. Vikings RB Dalvin Cook rushed for one yard on two carries in his first game since suffering a torn ACL last October. Good to see the rust coming off.

22. Texans DE J.J. Watt recorded one tackle in his own return to the field after missing 24 games over the past two seasons. “I liked that I came off under my own power,” Watt said afterward when I asked about his performance.

23. On the other side of the ball, Houston’s Deshaun Watson was decleated by Rams DL Ndamukong Suh. Watson was OK, but the Texans’ O-line could be an issue in front of a young quarterback coming off an ACL tear.

24. Niners CB Richard Sherman also returned to action as his comeback from an Achilles tear continues to progress.

25. Colts QB Andrew Luck had his best game of the preseason (8-for-10, 90 yards, TD), but questions remain about the quality of his supporting cast.

26. Assuming WR Marqise Lee’s knee injury was as bad as it looked, the Jaguars don’t have a player on their roster who caught more than 42 passes last season. Dez?

27. In more positive news, Jacksonville’s first-team defense has not allowed a preseason touchdown.

28. However Jags CB Jalen Ramsey did get a workout Saturday from Falcons QB (and 2016 league MVP) Matt Ryan, the same man Ramsey deemed overrated in a recent GQ article.

29. Bears WR Kevin White, who’s missed 43 of 48 possible regular-season games because of injuries after being drafted seventh overall in 2015, scored his first NFL TD on Saturday.

30. Bengals WR John Ross, the ninth overall pick in 2017, caught his first pro TD on Sunday after failing to register a reception in his rookie season.

31. Despite connecting on seven of 10 passes Saturday, Ravens rookie QB Lamar Jackson has a 47.2% completion rate. “We’ve seen it in practice where he’s done some really good things,” said Baltimore coach John Harbaugh. “We hadn’t really seen it in the game yet. He handled himself well.”

32. Standing on the opponent’s sideline will get you a delay-of-game penalty. Thanks to Dolphins LB Kiko Alonso for the knowledge.
