The defensive identity of the Arizona Cardinals during their historic Super Bowl XLIII run was forged in the disruptive energy of a third-round draft steal out of Florida State. Drafted 64th overall in the 2004 NFL Draft due to pre-draft character concerns that dropped his stock, Darnell Dockett arrived in the desert with a massive chip on his shoulder. He stepped onto the field and instantly evolved into one of the most explosive, penetration-style interior defensive linemen of his era.

Dockett had a quick, lethal first step that enabled him to penetrate gaps before offensive guards could establish their pass protection. Mainly functioning as an interior pass rusher, he used a combination of upper-body strength and aggressive hand techniques to collapse the pocket from the inside. Additionally, Dockett played with a relentless, fierce attitude that created an aggressive physical presence for the entire front seven.

His debut in 2004 made an immediate impression by securing a starting role and earning PFWA All-Rookie honors after recording 3.5 sacks and 39 tackles. His rise to elite status occurred in 2007, when he excelled at penetrating interior blocking schemes, achieving a career-high 9.0 sacks and 58 tackles, which led to his first Pro Bowl selection.

Dockett's standout moment came during the 2008 postseason on the sport's biggest stage. In Super Bowl XLIII against the Pittsburgh Steelers, he showcased an exceptional individual performance, tying the NFL Super Bowl record by sacking Ben Roethlisberger 3.0 times. His dominant play continued into the 2009 season, where he moved between defensive tackle and end, recording 7.0 sacks, earning Second-Team All-Pro honors and his second Pro Bowl invitation. He secured a third Pro Bowl selection in 2010, solidifying his role as a key interior defender early in the decade.

After missing the 2014 season due to a torn ACL, Dockett briefly joined division rival San Francisco in 2015. He was released before the start of the regular season and decided to return to Arizona, signing a ceremonial one-day contract in 2016 to officially retire as a lifelong member of the organization. Over ten seasons with the Cardinals, he accumulated 40.5 sacks, 459 tackles, 7 forced fumbles, and 4 interceptions across 158 games.

Before the "Air Coryell" offenses of the mid-1970s captivated the football world, the trench work in St. Louis was anchored by a quiet, unheralded draft steal out of Illinois. Selected in the 13th round (176th overall) of the 1961 NFL Draft, Ernie McMillan arrived at training camp as a converted college tight end. The Cardinals quickly shifted his 6-foot-5, 275-pound frame to offensive tackle, unleashing a cerebral, technically sound blocker who would anchor the edge for fourteen consecutive seasons (1961–1974).

The mechanics of his play relied heavily on leverage, geometry, and exceptional lateral balance. In an era where pass protection was a hand-to-hand brawl against legendary edge rushers, McMillan excelled through calculated body control and precise angles. He was a textbook technician who mastered the art of mirroring pass rushers, once grading out at a staggering 96 percent efficiency on pass blocks across a single season. His endurance was equally remarkable; after taking over as the full-time starter in his second year, he set a franchise record by starting 162 consecutive games without missing a single contest due to injury over his first twelve seasons.

In a testament to his selflessness and leadership, McMillan willingly moved from his longtime right tackle slot to left tackle late in his St. Louis tenure to accommodate the rise of young star Dan Dierdorf. That positional sacrifice allowed the Cardinals to field one of the most formidable tackle tandems in league history. After a final 1974 season in St. Louis where he helped secure a division title, he finished his career with a brief stint in Green Bay in 1975, retiring with 190 career regular-season games.

Marshall Goldberg, a two-time consensus All-American and Heisman Trophy finalist under Jock Sutherland at Pitt, became a national star when the Chicago Cardinals picked him in the 1939 NFL Draft's second round. As one of the earliest notable Jewish superstars in pro football, Goldberg's unique blend of backfield strength, return speed, and defensive savvy quickly boosted the team's competitiveness.

Goldberg had a low, powerful running style that made him effective between the tackles, combined with the quick acceleration of a track athlete. His versatility enabled him to play as a fullback, halfback, kick returner, and safety effortlessly. On defense, his quick decision-making and knack for turnovers made him a persistent threat to intercept passes from opponents, while his open-field tackling often stopped large plays in their tracks.

His multi-phase versatility peaked during the 1941 season. Goldberg delivered an impressive single-season performance, rushing for 427 yards, catching passes for 313 yards, and leading the NFL with 290 kickoff return yards. His total of 1,236 all-purpose yards topped the league, earning him a Pro Bowl spot and All-Pro honors. Not satisfied with offensive dominance alone, Goldberg also excelled on defense, tying for the league lead with 7 interceptions. He carried this exceptional energy into 1942, finishing fifth in all-purpose yards and continuing to excel in the secondary.

During his prime, Goldberg paused his football career to serve in the U.S. Navy for two years in the South Pacific during World War II. After returning to Chicago in 1946, he chose to play primarily as a safety to support the Cardinals' renowned "Dream Backfield,” which included Charley Trippi, Paul Christman, Elmer Angsman, and Pat Harder. His unselfish switch to safety became the defensive cornerstone of the memorable 1947 season, ending with a thrilling victory over the Philadelphia Eagles that secured the franchise's only NFL Championship to date.

Goldberg played one more season before calling it a career. He recorded 1,644 rushing yards, 775 receiving yards, 1,083 return yards, and 19 interceptions across 77 regular-season games. The Cardinals enshrined Goldberg into their Ring of Honor in 2006.

After setting the University of Miami school record as the first player in Hurricanes history to break the 1,000-yard mark, Ottis Anderson entered the professional ranks with immense expectations. Selected eighth overall in the first round of the 1979 NFL Draft by the St. Louis Cardinals, Anderson stepped into the backfield and instantly altered the physical identity of the franchise.

Anderson was the ultimate blend of power-back violence and open-field elusiveness. Running with a high-knee stride, lower-body drive, and sharp vision, he routinely punished defenders at the second level and had enough top-end speed to erase angle pursuits. Beyond his rushing volume, his smooth hands out of the backfield made him a lethal dual-threat weapon on third downs.

His professional debut in 1979 was one of the most remarkable in NFL history. In his very first regular-season game against Dallas, Anderson made an immediate impact with 193 rushing yards. He finished the season with a career-best 1,605 rushing yards and 1,913 total yards from scrimmage, earning AP NFL Offensive Rookie of the Year, a First-Team All-Pro honor, and his first Pro Bowl selection. Additionally, both UPI and The Sporting News named him NFC Player of the Year.

Anderson maintained a demanding workload into his 1980 sophomore season, rushing for 1,352 yards and 9 touchdowns while also catching 36 passes, earning his second Pro Bowl. During his first six seasons with St. Louis (1979–1984), Anderson exceeded 1,000 rushing yards five times, an achievement that would probably have been six straight if the 1982 strike hadn't shortened the season.

This set the stage for four years of consistent, high-volume production from 1981 to 1984. Anderson started the 1981 season by rushing for 1,376 yards and gaining 1,763 yards from scrimmage, becoming the franchise's all-time leading rusher halfway through his third season. In the strike-affected 1982 season, he helped keep the offense active with 587 rushing yards in just eight games, equivalent to a 1,000-yard season—and played a key role in leading the Cardinals to the playoffs. Fully healthy again, he posted consecutive 1,000-yard seasons in 1983 (1,270 yards) and 1984 (1,174 yards), anchoring a potent Big Red offense alongside quarterback Neil Lomax and establishing himself as an essential offensive force.

After injuries slowed his production in mid-1985 and 1986, the Cardinals executed a surprise mid-season trade, sending their legendary back to division rival New York. While his initial stint with the Giants was spent in a situational role, Anderson engineered a famous second act, winning the 1989 NFL Comeback Player of the Year Award and capturing Super Bowl XXV MVP honors in 1991.

He accumulated 7,999 rushing yards, 2,495 receiving yards, 10,494 yards from scrimmage, and 53 total touchdowns across 99 games as a Cardinal.
