Selected second overall in the 1978 NFL Draft following a Consensus All-American run at Kentucky, Art Still stepped directly into Arrowhead Stadium carrying towering expectations. Standing an intimidating 6-foot-7 and weighing 250 pounds, the imposing defensive end had rare reach and closing speed, quickly becoming the primary pass-rushing pillar for Kansas City's defensive front throughout the late 1970s and 1980s.

Still wasted no time asserting his physical dominance at the professional level. Anchoring the left side of the line, he generated 9.5 sacks during his 1978 rookie campaign and followed it up with 8.5 in 1979, using his massive wingspan to shed edge blockers and collapse pockets before quarterback scrambles could even materialize.

His national breakthrough materialized during a stellar 1980 campaign. Still earned his first Pro Bowl selection, an AP Second-Team All-Pro nod, and team MVP honors after terrorizing opposing backfields for a career-high 10.0 sacks (unofficial). Opposing offensive tackles routinely struggled to combat his long-arm bull rush and violent shed techniques along the perimeter.

Still matched that elite level of play in 1984, orchestrating his finest personal season in Missouri. He set a career high with 14.5 sacks, earning his second AP Second-Team All-Pro selection and another Chiefs Team MVP award. Across his ten-year tenure with the organization, Still surpassed the double-digit sack threshold twice and collected four total Pro Bowl honors (1980, 1982, 1984, 1985) as one of the league's premier edge rushers.

After ten seasons in K.C., Still was traded to Buffalo prior to the 1988 season, where he spent his final two professional campaigns providing veteran edge depth for a rising Bills contender before retiring. He was inducted into the Kansas City Chiefs Hall of Fame in 1998.  Statistically, Still gave the Chiefs 16 forced fumbles and 74 sacks.
