We're not sure when Houston will erect its own Mt. Rushmore for sports legends, but we're quite certain that J.J. Watt, who announced his retirement on Tuesday, December 27, and his chiseled countenance will one day jut from the rocky sculpture.

A no-brainer for the NFL Hall of Fame and arguably the greatest player to ever don a Houston Texans uniform (the other being the quiet great Andre Johnson), Watt broke the news on social media, where he posted heartwarming photos of he, wife Kealia, son Koa, and his family.

He stunned the football world — and fans — with this simple message and those family photos taken after his current team the Arizona Cardinals lost to the Tampa Bay Buccaneers:

Koa’s first ever NFL game. My last ever NFL home game. My heart is filled with nothing but love and gratitude. It’s been an absolute honor and a pleasure.

For many in Houston, it's still a bit surreal to see Justin James Watt — the NFL superstar drafted in the first round in 2011 by the Texans — in Arizona. (A pick that put this publication on the national map for all the wrong reasons with an embarrassing hot take).

After an understandable but still bittersweet release in February 2021, Watt made headlines by signing with the Cardinals, a move many applauded, given the Texans' downward trajectory.

Renowned for his relentless motor, Navy SEAL-type work ethic, team-first approach, and straight-up bulldozing and game wrecking, Watt quickly became a one-man nightmare for opposing coaches and players. Even Hollywood jumped on the WattWagon, with Arnold Schwarzenegger calling Watt a future action star and offering some motivation after a big playoff loss.

His Pick 6 play during the Texans' first-ever playoff game, where he batted down a pass from Cincinnati Bengals quarterback Andy Dalton and rumbled in for a touchdown, not only served as a terrifying calling card for the rookie, but would later inspire one his many nicknames: "J.J. Swat."

He would soon become one of only three players in NFL history to win at least three AP NFL Defensive Player of the Year Awards, in 2012, 2014, and 2015. In 2014, he made such a splash that he came in second overall for NFL MVP, a rare feat for even the best defensive players.

His stats are nothing short of Hall of Fame-ready. He leads the NFL in tackles for loss (172), quarterback hits (281), multi-sack games (26) and sack yards (713.5), while ranking second in sacks (101.0). In 2020, Watt, who led the NFL in sacks twice (2012 and 2015), became the fourth-fastest player in NFL history to total 100.0 sacks, doing so in just his 120th career game, per team stats.

As the NFL Network notes, Watt will retire as only of three players in NFL history to win Defensive Player of the Year three times. Add to that his five first-team All-Pro honors, five Pro Bowl trips, and his status as a two-time NFL sack leader (his 74.5 sacks over that span of time are the second-most since 1982.)

But for all his numbers, perhaps the most significant for No. 99 is $41.6 million: the amount he raised in 2017 for Hurricane Harvey relief — the largest crowd-sourced fundraiser in history. What started as a simple ask for help after the storm became a runaway, feel-good charitable moment across the country — a testament to Watt's superstar power and his ability to influence the public and raise awareness.

One part single-man football army, one part Captain America, Watt evolved into the epitome of the athlete doing it right — on the field and off (even his "Dream Big. Work Hard." Twitter bio is a simple lesson for young athletes everywhere), deftly navigating the intersection of sports and pop culture. Flashing his boyish grin and monstrous biceps, he was a natural fixture on local and national TV commercials, and a viral sensation with ominous warnings to opponents, like this scary "ya mess with me..." declaration in 2014.

Not since Earl Campbell has Houston seen an NFL player put his team and city on his broad shoulders. At six-foot-four and 280 pounds, Watt is a literal and figurative Houston giant, one who cemented all-time hero status with deeds over words, giving over taking, and always being gracious to those across the world who adored him.

The 33-year-old husband, father, and sports powerhouse may be calling it a career in Arizona, but he'll always be a Houstonian — and one of the greatest pro athletes to ever call the city home. Here's hoping if baby Koa Watt elects a career in pro football, he gets a call from Houston on draft night.
