The 2021 NFL season may still be months away, but fans can begin eagerly circling their calendars in anticipation of some truly mouth-watering fixtures after Wednesday's schedule release.

There are some obvious standouts. The Week 4 meeting of Tom Brady's Tampa Bay Buccaneers and Bill Belichick's New England Patriots should capture the entire league's attention as Brady returns to Foxborough for the first time since saying a shock farewell to his home of 20 seasons last offseason, and then going on to win a seventh Super Bowl ring in his maiden season with the Bucs.

A potential duel between Patrick Mahomes and the Kansas City Chiefs and Aaron Rodgers and the Green Bay Packers in Week 9 hinges on Rodgers blinking in his staring contest with the Packers' brass and returning for the season.

Should he do so, it will pit the reigning MVP against the 2018 MVP and Super Bowl LIV MVP in a matchup of two quarterbacks who have each recently finished in the top five in well-thrown ball percentage. Rodgers was third in the NFL with 82.4 per cent last season while Mahomes was fourth with 81.1 per cent in 2019 as he led the Chiefs to the Lombardi Trophy.

But the games with the best narratives on the surface do not always produce the best matchups. Here, using Stats Perform data, we look at five other games on the schedule that are in the mix to be among the most exciting games of the 2021 campaign.

Packers @ 49ers - Week 3

The Packers trounced a 49ers team decimated by injuries last season, though that was probably hollow revenge for Green Bay's NFC Championship Game humbling at the hands of San Francisco in the 2019 season.

Typically, when Rodgers has visited the team he idolised in his youth, things have gone poorly for the Packers. He has won two of his four regular-season meetings with the Niners in the Bay Area but has lost to San Francisco on each of the three occasions he has faced them in the playoffs, with two of those defeats on the road.

Still, if Rodgers acquiesces in his stand-off with Packers management and plays for Green Bay in 2021, it promises to be a fascinating duel of NFC contenders, with the Niners potentially starting a rookie quarterback in dual-threat Trey Lance.

Should Rodgers remain with the Packers, the key matchup in this one could well be the reigning MVP against a Niners defensive line that should get back edge rusher Nick Bosa after he missed most of the 2020 season with a torn ACL.

Rodgers' well-thrown percentage under pressure was 71.0 per cent in 2020, the ninth-best in the NFL, and he will likely have to maintain that accuracy under duress if Bosa is back to his best. The 2019 Defensive Rookie of the Year had a pressure rate of 28.3 per cent in his first season in the league, trailing only Adrian Clayborn and elder brother Joey, and sacked Rodgers in the regular season and the NFC title game.

Buccaneers @ Rams - Week 3

Yes, Brady v Belichick is the game everybody in Tampa will be most excited for, and the season opener between the Super Bowl champions and the Dallas Cowboys will be a primetime ratings monster, but perhaps the best duel involving the only player with seven Super Bowl rings will take place when Tampa head west.

The Rams edged the Buccaneers 27-24 in Tampa last season and should provide a stern test again at SoFi Stadium with Matthew Stafford set to be under center for Los Angeles.

But Stafford is not the person Brady will be concerned with when it comes to the Rams. Instead, it will be three-time Defensive Player of the Year Aaron Donald.

Brady was phenomenal when it came to avoiding interceptable passes last season.

He threw a pickable pass on just 13 of 590 pass attempts in 2020, a percentage of 2.20 that only Alex Smith (2.12) could better. When under pressure, it increased to 3.45 per cent, but that was still the fourth-lowest pickable pass rate in the NFL under duress.

But no defender in the league strikes fear into the heart of quarterbacks quite like Donald, who led all defensive tackles in 2020 with a pressure rate of 27.7 per cent and an adjusted sack rate of 5.5 per cent.

Donald can destroy the best-laid plans of any offense, and surviving the challenge he and the Rams will pose will be one of the biggest tests for Brady and the Bucs in their bid to repeat as champions

Bills @ Chiefs - Week 5

This is a rematch of last season's AFC Championship Game in which the Bills did not produce an effort reflective of their outstanding 2020, and Buffalo look like the team best placed to challenge Kansas City again in the AFC in 2021.

The headline act of this clash is the battle of the quarterbacks, with Mahomes and Josh Allen leading the revolution of athletic, cannon-armed quarterbacks who have taken the league by storm.

But an underrated aspect of this game will be Stefon Diggs' performance against a Chiefs secondary that does not get the credit it deserves.

Diggs was held to six catches for 77 yards in the playoff matchup but recently revealed he played through the postseason with an oblique tear.

When healthy, Diggs has the ability to do significantly greater damage. He led the NFL with 1,535 receiving yards in his first season in Buffalo and trailed only Davante Adams (3.9) in burn yards per route as he averaged 3.6.

However, the Chiefs' projected starting cornerbacks have the means to slow him down. L'Jarius Sneed was fifth among all corners in preventing big plays, allowing a play of 20 yards or more on just 14.5 per cent of his targets. 

Meanwhile, Charvarius Ward was fourth among corners in burns allowed, giving up a burn on 32.7 per cent of his targets.

Bears @ Seahawks - Week 16

The Bears have rarely been high on the list of teams to look out for when it comes to intrigue in recent years, but that all changed when they traded up to draft Justin Fields 11th overall.

Once Chicago ends the charade of committing to Andy Dalton as starting quarterback and goes with the high-upside rookie, the Bears have the potential to be an extremely interesting watch.

That will certainly be the case if Fields is under center when they travel to Seattle's Lumen Field, with the Bears set to face the quarterback they reportedly pursued before picking Fields, Seahawks star Russell Wilson.

A quarterback battle between Fields and Wilson has the potential to be an absorbing encounter featuring two signal-callers who each excel with their accuracy throwing the deep ball.

Of quarterbacks with at least 25 throws of 25 or more air yards, only three players (Ryan Tannehill, Philip Rivers and Derek Carr) had a higher well-thrown percentage than Wilson's 63.0 per cent on those attempts last season.

Fields was similarly proficient attacking downfield in his final year for Ohio State, posting a well-thrown percentage of 76.47 per cent on throws of 15 or more air yards that was superior to that of Trevor Lawrence, Zach Wilson and Mac Jones.

If his success in that regard quickly translates to the NFL, the Bears' trip to the Pacific Northwest could turn into a scintillating showcase of the deep passing game. For the first time in a while, the Bears have the potential to be must-see TV.

Ravens @ Browns - Week 14

The balance of power in the AFC North is shifting towards the Ravens and Browns and their Monday Night game in Cleveland last year was among the most entertaining of the 2020 campaign.

In the end, the Browns' inability to stop Lamar Jackson, even after his apparent 'comfort break', from making the big plays in Baltimore's thrilling comeback was the decisive factor in the Ravens' 47-42 triumph.

Cleveland took steps to stop such a scenario from playing out again, using their first-round pick on a cornerback in Greg Newsome II who allowed a big play on just 4.2 per cent of his 36 targets in an abbreviated final season at Northwestern.

His addition, and that of versatile second-round linebacker Jeremiah Owusu-Koramoah, who allowed a big-play percentage of 11.0 when covering from the slot and had an overall pressure rate of 25.0 per cent, should help the Browns do a better job of slowing down opponents.

But whether those arrivals are enough to make the difference against Jackson and the Ravens is another matter.

An underrated downfield thrower whose well-thrown percentage of 60.0 on throws of 25 or more air yards was seventh in the NFL last year, Jackson has another dynamic weapon to target in the form of first-round receiver Rashod Bateman.

Sixth among Power 5 wideouts with at least 50 targets in burn yards per target (16.15) in his stellar 2019 season, Bateman can be the number one receiver Jackson has long since lacked.

Bateman excelled at creating separation two years ago while having an average depth of target of 16.2. With him and speedster Marquise Brown in the mix, Jackson does not lack big-play weapons, and Cleveland's ability to keep them under wraps could be critical in deciding an ultra-competitive division in 2021.
