With graduate school being done for the summer, I have a lot more free time to do stupidly entertaining stuff like this. Making this took me way longer than I would ever want to admit so please indulge me. Also, I'm happy to debate about any comparison that I made.
Troy Aikman as Ned stark
As beloved recent historical figures of the NFL/Realm, Troy Aikman left a legacy with the Cowboys that can be compared to the legacy Ned left with his House and all of Westoros.
Jerry Jones as Robert Baratheon
Just like Jerry, Robert likes to have a good time.
Shaquem Griffin as Jaime Lannister
Not only do Shaquem and Jaime both have an amputated hand, but they both always find a way to stay with their siblings.
Catelyn Stark as Michael Irvin
Catelyn Stark was the Michael Irvin to Ned Stark's Troy Aikman. Ned could always count on her to be there for their House.
Eli Manning as Cersei Lannister
Once regarded as a great, like Cersei, Eli has now crumbled under the house he helped build.
Archie Manning as the Lord of Light
Watching over his sons, he drives their ultimate purpose of achieving Superbowls.
Peyton Manning as Beric Dondarrion
"Somehow", despite injuries, Peyton Manning was able to keep resurrecting his football game. Perhaps this was because of the Lord of Light, Archie Manning, or maybe it was because of his wife injecting him with steroids.
Cooper Manning as Rickon Stark
The brother everyone forgot about.
Patrick Mahomes as Daenerys Targaryen
The only one capable of stopping House Patriots and rivaling the Night King 12's power. Both are so close to the Throne, but the future is still uncertain.
Larry Fitzgerald as Ser Jorah Mormont
With 16 years of professional football under his belt, Fitzgerald is STILL loyal to the Arizona Cardinals. Despite being friend-zoned for eight long seasons, Jorah remained loyal to his now seemingly doomed Khaleesi and died fighting for her. We expect Larry to do the same for the seemingly doomed Cardinals.
Mark Sanchez as Viserys Targaryen
Being a douche to Daenerys was Visery's version of the butt fumble - never forgotten.
Colin Kaepernick as Jon Snow
Bending the knee is a controversial topic for both of them.
Joe Gibbs as Sansa Stark
Head Coach Joe Gibbs made it to the Superbowl three times despite having three different starting QBs. Meanwhile, the Lady of Winterfell, Sansa Stark, achieved her status despite having three different husbands.
Rob Gronkowski as Arya Stark
They both got like seven concussions last season.
Anthony Dorsett as Robb Stark
As the son of Hall of Fame Cowboys RB, Tony Dorsett, Anthony had a strong lineage and a legitimate claim to the Superbowl - however he fell short of the title, just like Robb Stark, eldest son of Ned Stark.
Jon Gruden as Bran "The Three-Eyed Raven" Stark
Both claim to be "all knowing" but neither really are much help when it's truly needed.
The Browns as Theon Greyjoy
Once respected, the Browns and Theon began to reek. However, after some off season moves and redemptive actions, both are once again on the road back to glory
Odell Beckham Jr. as Queen Yara Greyjoy
They both love boats and they like to switch to the winning teams.
John Harbaugh as Balon Greyjoy
Part of a historically powerful families, these men have to deal with brothers with big personalities.
Skip Bayless as Euron Greyjoy
Both just fill a room with a lot of hot air.
Johnny Manziel as Joffrey Baratheon
Warning: Choking Hazard.
Nothing like Heisman-winning entitlement issues to kill your chances of making it in the big leagues.
Von Miller as Sandor "The Hound" Clegane
They both really like their chickens. And they both are savages on the playing field.
Aaron Donald as Ser Gregor "The Mountain" Clegane
Absolute monsters. Created to destroy everything in their path - whether it's offensive linemen or the cocky Oberyn Martell.
Darren Sproles as Tyrion Lannister
Little but mighty. And surprisingly smart.
Travis Kelce as Khal Drogo
Huge, clutch, and arrogant.
Terrell Owens as Petyr "Littlefinger" Baelish
Damn, they are so good at what they do but every team/house cuts them because the are they are a cancer to the locker room.
Jason Witten as Ser Davos Seaworth
Jason Witten is among the most liked players in the NFL, while Davos is one of the most liked characters in Westoros. Both having troubled upbringings, they both rose from the Flea Bottoms and made a name for themselves. Although, Davos is the only one who should pursue any sort of career in public speaking.
Andrew Luck as Samwell Tarly
Both have outrageous neck beards. Both love to read. Would probably be best friends.
Alex Smith as Eddison Tollet
Eddison, the new Lord Commander of the Night's Watch, died in battle. Alex Smith, the new 2018 starting QB of the Redskins, got sacked in week 11 removing him from the rest of the 2018 season and also the 2019 season. RIP Eddison and Alex Smith's Career.
Philip Rivers as Stannis Baratheon
Hall of Fame potential? Eh kind of. Could they have taken the throne? Sure, but no. Did they get overshadowed? Shout out to Melisandre and Drew Brees.
Robert Griffin III as Renley Baratheon
Frank Gore as Melisandre "The Red Woman"
Despite being super freaking old, they defy their ages and perform - sometime's even resurrecting their team or their boy Jon Snow.
Roger Staubach as Jeor Mormont
The Lord Commanders of their profession, they're iconic figures that led the people to victory.
Le'Veon Bell as Bronn
Like Bronn, Le'veon's loyalty can be bought. To prove their stubbornness, they both will sit out of seasons/episodes.
Adam Schefter as Varys
Can always count on their little birds to feed them information. Hopefully Schefter doesn't use children though.
Bill Belichick as Lord Tywin Lannister
The masterminds behind the most powerful houses in the NFL and Westoros, Tywin and Bill are highly regarded for their stern personalities and superior war tactics.
Julian Edelman as Shae
Shae is a tool that Tywin (Bill) used to retain the throne
Tom Brady as The Night King
The looming threat against all teams, whether the living or Bills fans, Tom Brady and the Night King will eventually get hit and shatter into a million pieces. Not to mention, both have dragon killing arms.
Russell Wilson as Margaery Tyrell
Subtly trying to make their way to stop by playing well and making people like them but blow it on an interception.
Howie Long as Lady Olenna Tyrell
Both created families that rule the seven kingdoms of Westoros and the 8 divisions of the NFL.
Josh Allen as Ygritte
Helps lead the Wildings in the brutally cold north to victories.
Baker Mayfield as Lord Gendry Baratheon
Nice guy. Has a few weapons in his arsenal. Might take the iron throne, might not. Although, Baker Mayfield's girlfriend at least accepted his proposal to make her the Lady of the Browns.
Ryan Fitzpatrick as Tormund Giantsbane
FEAR THE GINGER BEARD
J.J. Watt as Ser Brienne of Tarth
Tall, blond and absolutely dominant on the field. Honestly, Ser Brienne may be JJ Watt's long lost twin sister.
Josh Gordon as Gilly
Not really sure what she's good for except mild viewer entertainment.
Randy Moss as Daario Naharis
Jumped into bed with a person/team and fell in love, only to spit out and forgotten. Big oof.
Marshawn Lynch as Missandei
Doesn't say much but they do their job well.
Cam Newton as Prince Oberyn Martell
Oberyn and Cam are both extremely passionate people, but on the biggest stages of their careers they found themselves defeated.
Joe Flacco as Ellaria Sand
Like they’re cool, but not elite.
Cody Parkey as Tommen Baratheon
When put on blast, neither could handle the pressure.
Tony Romo as Jaqen H'ghar
Tony Romo is a man of many faces. One moment he's an NFL QB, next he's a Monday Night Football commentator, then he's a professional golfer.
Roger Goodell as The High Sparrow
Suspending people and lacking justification in their actions is kind of their thing.
Jadeveon Clowney as Grey Worm
They both just fn scare me.
"Big Dick" Nick Foles as Podrick Payne
Need I say more?
Emmitt Smith as Meera Reed
Meera and Emmit provided the support that their teams needed to survive and thrive.
CJ Anderson as Lady Lyanna Mormont
Prior to the Battle of Winterfell, Lyanna Mormont was underestimated because of her age and size, but during the heat of battle she stepped up and killed the Giant. Like Lyanna, CJ Anderson was underestimated because of his age and size, but during the heat of the playoffs he stepped up and carried the load for the injured Todd Gurley.
Andy Reid as Hodor
Andy Reid, an offensive mastermind, held the door open for the most useless character in the NFL, Chip Kelly, to take the reigns of the Birds.
Khalil Mack as Drogon
The weapon that every team needs. Moved north to lead the NFC Northerners to victory against the dead.
Saquon Barkley as Ghost
Just like Ghost, Saquon was neglected by his owners and now has to deal with a shit show.
Side note: Jon Snow really should've pet ghost.
Jay Cutler as Hot Pie
Nobody is really sure what they're good for, but they're nice to have around.
Aaron Rodgers as Aaron Rodgers
