Three weeks down, one to go.
Some teams rested their starters, but most played their first team for an extended period as a dress rehearsal for the regular season. The result was the summer's most intriguing slate of games.
Here are the biggest takeaways from all 16 contests:
Browns 5, Eagles 0
Nick Foles may have lost his magic. We know, preseason statistics don't mean a whole lot, but Foles was dreadful against the Cleveland Browns, throwing two interceptions and struggling under pressure.
If star quarterback Carson Wentz isn't cleared for Week 1 - or suffers a setback during the year - the defending Super Bowl champions could have trouble replicating the offensive production from their 2018 playoff run. The Eagles may need Foles, but he's yet to show he can be relied on this summer. - Alessandrini
Panthers 25, Patriots 19
Will someone please tell Cam Newton it's the preseason. The quarterback, once again, needlessly put his body, as well as the Carolina Panthers' season, on the line by leaping head first on a scramble.
Newton was fine, but it was a painful reminder that the quarterback still needs to be saved from himself. And considering the Panthers' offensive line suffered another injury, this time to Jeremiah Sirles, Newton should be avoiding extra punishment at all costs. - Browne
Giants 22, Jets 16
The rookie didn't exactly impress with his steady performance against the Giants, finishing 8 of 16 with one touchdown pass, but the reality is, he didn't need to.
In fact, Darnold's turnover-free play likely bolstered the Jets' confidence that he's ready for the rigors of being a first-year starter. Where this leaves Teddy Bridgewater, who also played well, remains to be seen. - Browne
Broncos 29, Redskins 17
It likely says more about the current state of the Washington Redskins' backfield than Adrian Peterson's skill set, but the former NFL MVP looked like the team's best runner in an impressive preseason debut.
Peterson averaged 5.1 yards on 11 first-half carries, including a 15-yarder in which his patented uber-violent running style was on display.
