The 40 things we learned from Week 1:

1. Raiders coach Jack Del Rio … our Week 1 hero. That took, well, you know.

2. As far as first impressions go, Philadelphia's Carson Wentz couldn’t have asked for a better start — especially against the Browns, who didn't think he'd develop into a top 20 quarterback.

3. Jameis Winston > Marcus Mariota.

4. Rex Ryan. Hot seat. Some things never change.

5. That stadium ballot measure in San Diego? Blowing a lead (and game) like they did in Kansas City not quite the campaign message the Chargers are looking for at this point.

Armour: Why did Browns pass on Carson Wentz?

6. Cowboys RB Ezekiel Elliott talked a big game before Sunday. Not quite the force he thought he would be, huh? This isn’t the Big Ten anymore, Zeke.

7. For the record, the Kansas City Chiefs were the first team to put points on the board in the early games: A field goal.

8. Philadelphia was the first team to score a TD in the early games, a TD pass from Wentz.

9. Rodgers to Nelson for Packers TD. And all of Green Bay smiles.

10. This Cardinals play earned a penalty for a "choreographed celebration." We don't expect to see these moves on wedding dance floors any time soon.

11. The Ravens out-gained Bills 114-2 in the first quarter but led only 3-0. Didn’t matter, though, because the Bills are still the Bills.

12. Food for thought: Seahawks win with 12 points. They call their fans the 12s. When they won the Super Bowl three years ago, they scored 12 points in the opener. Where else can you get this kind of inside info?

13. Another sign it will be another long season for NFL officiating guru Dean Blandino: During a field-goal attempt by the Eagles, the ref beneath the right upright signaled no good, but his buddy under the left upright signaled good. It was no good. Wide right. (At least they got it right without a 10-minute discussion).

Terrance Williams' blunder costs Cowboys as Giants hold on

14. Brock Osweiler’s first drive as a Texan: Interception. And all Houstonians shook their heads.

15. They felt much better later in the second quarter when he threw a great TD pass to DeAndre Hopkins in the corner of the end zone.

16. Talk about throwing shade. This tweet from former Cowboy Deion Sanders after WR Terrance Williams did not even try to get out of bounds and the clock ran out on Dallas: “Everybody ain't built for the moment. WOW #Truth”

17. Respect for the NFL for the classy 9-11 salutes.

18. Respect to the players who chose to join “the Kaepernick protest.”

19. And, yes, it is possible to respect both. #America.

20. Victor Cruz. Salsa. Welcome back.

Raiders deserve praise for bucking NFL trend with bold two-point try

21 Terrelle Pryor continues to show great potential as a receiver. If you haven’t seen his second quarter catch that set up the Browns’ first TD, go tune into the highlights.

22. Antonio Brown is a real threat to put up 2,000 receiving yards.

23. The Chargers used all their first half timeouts with more than 11 minutes to go in the second quarter. Andy Reid was the opponent, so maybe it was a nod to him and his clock management.

24. Bucs TE Austin Seferian-Jackson snagged a beautiful TD catch in the third quarter. Bucs fans were like, “finally.” But opponents better watch out if he finally realizes his potential and becomes another weapon for Jameis Winston.

25. Some things never change: Kickers still missing easy field goals all over the league. You have one job to do …

26. As if by script, Vikings kicker Blair Walsh — he of the infamous playoff shank — missed his first chance of the season, a 37-yard field attempt. Wide left. Laces were out. Walsh also missed a 56-yard try, not that you can blame him for that.

Armour: NFL players protest on 9/11, and that's fine

27. To his credit, Walsh hit his next four field goals to help the Vikings to a big road win at Tennessee. (But you better work on those PATs, Blair.)

28. A tip of the helmet: Titans linebacker Avery Williamson wore patriotic spikes despite the threat of being fined.

29. Speaking of Aaron Rodgers, make sure you catch his TD throw with Jags rookie Jalen Ramsey hanging on to him. Classic Favre, er, Rodgers.

30. Melvin Gordon touched the ball 219 times in his career before scoring a touchdown. That is fourth most by any player in the last 25 years, according to Elias Sports. But Gordon did get into the end zone twice on Sunday.

31. The Bengals-Jets game was a great Week 1 battle. That is all.

32. Speaking of the Jets, they finished with seven sacks (five in first half) and Sheldon Richardson didn’t even play. That line is a force.

33. Chargers WR Keenan Allen injured. Badly. Again. Sad.

34. Drew Brees threw a 98-yard touchdown pass to Brandin Cooks. Who dat!?, indeed.

35. Think this is Russell Wilson’s offense now? Need proof? Seattle threw 26 times in the first half, the first time he has done that.

36. Hey, Jared Goff, you might be better off struggling more in practice this week, because you probably don't want to play on this offense sooner than you have to.

37. Fun fact from the NFL PR office: Oakland is the fourth team to score game-winning points on a two-point conversion in game's final minute (first in a season opener).

38. By the way, maybe Rob Ryan wasn’t the only problem with the Saints defense. Shocking, we know.

39. And, of course, there was one of those Eli Manning interceptions you knew was coming. This one led to a Cowboys touchdown and gave Dallas a third-quarter lead. But Manning came back to toss the game-winning TD to Cruz, and the Giants beat the Cowboys in Week 1 for the first time in nine tries dating to 1965.

40. That was a big road win in Indianapolis for the Lions. The kind that could change the course of their season. We'll see.
