From one of the most jaw-dropping offensive displays in NFL history, to a pair of gender-barrier breakers in the collegiate ranks, to a Taylor Swift sighting, it was a fascinating weekend of football on both sides of the border. Here are some of the highlights:

The Miami Dolphins dropped a 70 burger on Denver. Quarterback Tua Tagovailoa threw four touchdown passes while running backs Raheem Mostert and De'Von Achane scored four TDs each as Miami routed the hapless Broncos 70-20 on Sunday. The Dolphins fell a field goal short of the NFL record for most points in a game by one team but still racked up the league's highest single-game total since 1966. Clear your calendar for this Sunday at 1 p.m. ET, when Miami (3-0) visits rival Buffalo (2-1). The NFL's most lethal offence will face a fierce Bills defence that forced five takeaways and piled up nine sacks in yesterday's 37-3 drubbing of Washington.

The Cowboys, Jaguars and Ravens suffered stunning upsets. Dallas had a claim to being the NFL's best team through two weeks after routing the two New York clubs by a combined score of 70-10. But the Cowboys got bucked 28-16 by winless Arizona, widely considered the league's worst team entering the season. That result wrecked a lot of survivor pools, along with Jacksonville's 37-17 blowout loss to Houston and Baltimore's 22-19 OT defeat to Indianapolis.

Taylor Swift cheered Travis Kelce and Kansas City on to a big win. It might be too early to call this a love story, but Swift accepted the All-Pro tight end's invitation to watch yesterday's game from a private suite alongside
