When he reported to Braves camp, Phil Niekro resisted throwing a knuckleball until he was given an ultimatum: 'throw the knuckler or go home.' He did, and instead of going home he went to the Hall of Fame. Niekro won 318 games over 24 seasons, spending 21 of them with the Braves. He was an All-Star five times, first at age 30 and his last selection at age 45, and won five Gold Gloves. Niekro was 81.

A key cog of the Celtics' early dynasty who went on to become the team's head coach, K.C. Jones' eight rings as a player are only surpassed by his Boston teammates Bill Russell and Sam Jones. K.C. Jones was Russell's teammate at the University of San Francisco and later joined him with the Celtics, where he was a playmaker and defensive stopper. He followed up his playing career by getting into coaching, and eventually returned to Boston where he coached Larry Bird's Celtics teams to two additional titles. An NCAA champion, an Olympic gold medalist and a Hall of Famer, Jones was 88.

Utah running back Ty Jordan was named Pac-12 offensive freshman of the year after amassing 723 total yards from scrimmage and scoring six touchdowns in just five games.

One of the most feared linebackers of his generation, Kevin Greene defied his status as a fifth-round draft pick, piling up sacks and earning a spot in the Hall of Fame. For 15 years, Greene terrorized quarterbacks while playing for the Rams, Steelers, Panthers and 49ers. He was an All-Pro twice and picked to play in five Pro Bowls. His 160 sacks are the third-most in NFL history. Greene was 58.

Best known as the man who replaced Paul 'Bear' Bryant at Alabama, Perkins is also credited with reviving the New York Giants, although his 23-34 record with Big Blue doesn't tell the whole story. Perkins, along with Giants GM George Young, laid the foundation for the team's championship years in the 1980s, drafting QB Phil Simms and LB Lawrence Taylor. When he left the Giants for Alabama to take over for Bryant in 1982, he handed the Giants off to Bill Parcells, who would cement his own status as a coaching legend. Perkins also hired Bill Belichick with the Giants. Perkins, who had dealt with heart issues, was 79.

A Rookie of the Year who blossomed into an MVP, Allen was one of the most feared hitters of his day and is widely regarded as one of the best players to not be in the Baseball Hall of Fame. Allen slugged 30-or-more home runs in six different seasons, including a 40 homer, 110 RBI. .317 batting average season for the Phillies in 1966. He finished fourth in MVP balloting that year, boxed out by a trio of Hall of Famers; Roberto Clemente, Sandy Koufax and Willie Mays. Allen's HOF case was hurt more by optics than production; part of it was tied to race, another part linked to rubbing the media (aka, the voters) the wrong way. Allen's No. 15 was retired by the Phillies in 2020. He was 78.

An American icon in the truest sense, Rafer Johnson won the decathlon at the 1960 Rome Olympics, played basketball for John Wooden at UCLA, appeared in movies alongside Elvis Presley and Frank Sinatra, and is widely known for subduing Robert Kennedy's assassin at the Ambassador Hotel in 1968. Johnson lobbied to bring the Olympics to Los Angeles in 1984, lighting the flame for the Games inside the Coliseum, and was on the organizing committee for the first Special Olympics. He also worked with the American Red Cross, March of Dimes, Muscular Dystrophy Association and the Peace Corps in addition to being a telecom executive. Johnson was 86.

Truly one of soccer's all-time greats, the Argentine led his country to a World Cup in 1986 with a swashbuckling style on and off the field. Famous for his 'Hand of God' goal, his run through the English defense four minutes later is widely regarded as one of the most breathtaking goals in the sport's history. For all of his brilliance on the field, he lived a life of excess away from it and his drug use and philandering, among other demons, became as much a part of his story as his athletic excellence. Through it all, he remained a legend in his home country. Maradona was 60.

Vince Lombardi's favorite player from his championship Packers teams, Paul Hornung was, in his coach's eyes, 'the best all-around back to ever play football.' Hornung starred at Notre Dame, where he won a controversial Heisman Trophy; he's the only winner from a losing team in the award's history, and won the award with just three touchdowns and 13 interceptions as a triple-threat quarterback. With the Packers, his career took off under Lombardi, and he was an All Pro in 1960 and 1961, the year he was also MVP, while winning championships in 1961, 1962 and 1965 before winning Super Bowl I. In 1963, Hornung was suspended for betting on games, but Lombardi welcomed him back to the team. Hornung, who suffered from dementia, was 84.

Few people are as much a part of a franchise's fabric as Heinsohn is for the Celtics. For generations of fans, he's the lovable Boston homer, doling out 'Tommy Points' during Celtics TV broadcasts. For older generations, he was a mainstay of the team's golden years, winning eight titles in nine seasons as a running mate alongside Hall of Famers Bob Cousy and Bill Russell, whom he'd later join in Springfield. Heinsohn, who was a part of all 17 Celtics championships, was 84.

Nicknamed 'Little Joe,' Morgan played bigger than his stature. The second baseman was a key cog of Cincinnati's Big Red Machine, winning two World Series in his eight seasons with the Reds. By the time he was done playing, Morgan, who also played for the Astros, Phillies and A's, had carved out a Hall of Fame career and established himself as one of the best second basemen of all time. Morgan, who went on to have a long broadcasting career, was 77.

A New York native who grew up to pitch for the Yankees, Ford won more World Series games than any pitcher in baseball history.

One of the most feared pitchers of his era, Gibson spent his entire 17-year career with the Cardinals, bringing two World Series to St. Louis. A fierce competitor who famously hated the All-Star Game, Gibson won two Cy Young awards and a National League MVP during his Hall of Fame career. He was the MVP of the two World Series the Cardinals won and finished his career with 251 wins, 3,117 strikeouts and a 2.91 ERA. His dominant 1968 season – 22 wins, 13 shutouts and a 1.12 ERA – led to MLB lowering the pitcher's mound from 15 to 10 inches. "I was pissed," he famously said of the move. Gibson, who revealed he had pancreatic cancer in 2019, was 84.

One of the most dynamic players in NFL history, Sayers immediately made an impact in the NFL, setting a rookie record with 22 touchdowns in 1965. The "Kansas Comet" got better from there. He was an All-Pro in each of his first five seasons and won two rushing titles. An electric kickoff returner, he retired as the league's all-time leader in return yards. Despite his career being cut short by injuries, Sayers was a first-ballot Hall of Fame selection in 1977. Sayers was 77 years old.

One of baseball’s signature leadoff hitters and base stealers, Lou Brock died at age 81 following a series of health complications. Brock helped the Cardinals win three pennants and two World Series titles in the 1960s, and was elected into the Hall of Fame in 1985. At the time of his retirement, he was basball's all-time leader in stolen bases with 938 and is still second on that list.

Tom Terrific, the greatest pitcher from the Mets' greatest era, died following a series of health complications. He was 75.

He won three Cy Young awards for the Amazins and led the 1969 "Miracle Mets" to the team's first World Series title. Seaver also pitched for the Reds, Red Sox and White Sox in his career. A 12-time All-Star, he was a near-unanimous Hall of Fame selection and is one of just 10 pitchers with more than 300 wins and 3,000 strikeouts.

It's an art to hit and not be hit.'

The winningest coach in NFL history, Shula led the Miami Dolphins to an undefeated, title-winning season in 1972 on his way to a league-record 347 victories. In his 33 seasons as a head coach, Shula posted only two losing campaigns. One of the great marks of Shula’s Hall of Fame career was his adaptability. His early Miami teams were built on defense and running (the 1972 team only threw the ball 259 times in 14 regular-season games), but he quickly changed to a passing offense when Dan Marino came to town. Shula, who won two Super Bowls with Miami, was 90. (AP Photo/ George Widman)

The real-life Nuke Laloosh, of "Bull Durham" fame, Dalkowski had a live arm and little control over it. Stories of Dalkowski's velocity were legendary – Cal Ripken Sr. said he threw harder than both Sandy Koufax and Nolan Ryan; Ted Williams said he was "the fastest pitcher in baseball history" – as were his bouts with wildness (he once threw 39 wild pitches in a minor-league game).
