Roger Goodell: King Joffrey
He's a blond-haired demon with an absurd amount of power. He takes far too much pleasure in being the judge, jury and executioner, and he gets booed every time he's in front of his subjects...and King Joffrey is pretty unpleasant too (see what I did there?).
Drew Rosenhaus: Lord Petyr Baelish
Sports agents (or talent agents in general) are typically stereotyped as conniving, greedy, backstabbing worms who test the rules and place their own needs ahead of the needs of the clients. They serve as key players in the negotiations of every single NFL contract, and therefore possess considerable power despite being disliked by most owners and general managers.
Lord Baelish, who fits that description, is not liked by the lords of Westeros or the other members of the small council—they simply tolerate him and surrender to the fact they must deal with him to get anything done.
Super agent Drew Rosenhaus does not appear to possess any of the aforementioned negative traits, at least based on his interviews and television appearances. However, any agent is a good fit as Lord Baelish, and Rosenhaus is the most powerful NFL agent around, so he gets the nod.
Adam Schefter: Lord Varys
Lord Varys is known in Kings Landing as the "master of whispers." He has sources all over Westeros—his "little birdies," as he refers to them—who feed him rumors and whispers, and he uses these rumors to advance his career and gain favor with the king.
ESPN's Adam Schefter, who frequently beats all reporters to the punch with his iPhone and lightening-fast Twitter fingers, is undoubtedly the NFL's version of the "master of whispers."
Eli Manning: Jon Snow
It's true, Jon Snow is far more awesome than Eli Manning could ever hope to be, but that doesn't mean the similarities aren't there.
Jon Snow spent his early years living under the shadow of his older brother, Robb Stark, and grew jealous of Robb's ability to excel in nearly every department. Snow was always exceptional in his own right, but he could never outdo his older brother. That is, until he traveled north to join the Night's Watch, where he established himself as the order's most skilled swordsman and helped them defeat the wildlings.
Manning spent his early years under big brother Peyton's shadow, but like Snow, he traveled north to play for the New York Giants and managed to establish his very own unique legacy.
Unfortunately, Eli doesn't own a direwolf named Ghost. He has his very own Jason Pierre-Paul, though, so that's probably close enough.
Dr. James Andrews: Grand Maester Pycelle
If a star player from your favorite NFL team sustains an injury that requires the immediate attention of an orthopedic surgeon, chances are his first phone call will be to the office of Dr. James Andrews, who is basically the Michael Jordan of sports injuries.
Likewise, when the knights of Kings Landing lose a limb or suffer a puncture wound from a Valyrian sword, their first stop is Grand Maester Pycelle's chambers.
It's unlikely that Dr. Andrews utilizes leeches or potions, and he certainly doesn't amputate the limb at the first sign of trouble, but overall, he and Maester Pycelle practically have the same profession—healing warriors—and that makes them a match.
Ndamukong Suh: Gregor "The Mountain" Clegane
Gregor Clegane, known by his nickname "The Mountain," is the largest, most ferocious warrior in all of Westeros. He has little to no class and has zero regard for the rules (he once stuck a joust through an opponent's throat during a friendly tournament, simply because he noticed the armor was loose and the opportunity was there).
To determine which player is the best fit for The Mountain, you have to ask yourself "which NFL lineman would frighten me the most in a back alley sword fight to the death?"
Ndamukong Suh is a very logical answer to that question. Not to mention, Suh has a well-known reputation as a dirty player who delivers questionable hits and takes shots after whistle—which fits The Mountain like a glove.
Ray Lewis: Sandor "The Hound" Clegane
Sandor "The Hound" Clegane is, perhaps, the most massive and ruthless knight in all of Westeros (other than his brother, The Mountain). He has the filthiest mouth in all the Seven Kingdoms, and few men dare stand in his way.
Ray Lewis retired from football following Baltimore's 2012 Super Bowl season, but Lewis consistently maintained his reputation as the baddest, meanest player in all of football throughout his 17-year career.
The intensity on Lewis' face alone is enough to frighten an opponent into submission, just as Hound's charred face sends children running for the hills.
