903 wins. It’s an unparalleled level of excellence in college basketball. Coach K and his mentor Bobby Knight occupy rarified air already, both touting 902 career wins. When that tie is broken, the bar will have been raised. This is one record that will take a long time to topple. Here is a look at some records that will never fall …

Cal Ripken Jr. broke Lou Gehrig's 56-year-old record of 2,030 consecutive games on Sept. 6, 1995 to become baseball's new Iron Man. His streak ended at 2,632 games when he voluntarily asked to be removed from the lineup for the final Orioles home game of the 1998 season. His streak spanned 17 seasons, all with the Baltimore Orioles. The active player closest to the record is the Dodgers' Matt Kemp whose span is 363.

Jerry Rice set many records in his playing career that will never be broken. His 1,549 receptions are 447 more than No. 2 on the list, Marvin Harrison, who is done with football. The 22,895 receiving yards he accumulated are 7,961 ahead of his former Raiders teammate and another Hall of Fame-caliber talent, Tim Brown. His 197 receiving touchdowns — that make up his otherworldly total of 208 total TDs — exceed Moss' by 44.
 

March 2, 1962, NBA great Wilt Chamberlain scored 100 points in a game, breaking his own record of 78 set just three months earlier. Kobe Bryant has come closest to that record, with an 81-point game against the Raptors in 2006.

Cy Young, the man for whom baseball's most coveted pitching award is named won an astonishing 511 games in his 22-year MLB career. Next closest on the list is Walter Johnson with 417. The 300-win club has 24 members, the most recent to join was Randy Johnson in 2009. Even that milestone seems unattainable now.

The Great One took over the the career-points lead on Oct. 16, 1989 by surpassing the 1,850 points set by the legendary Gordie Howe. Gretzky finished his career with 2,857. Next closest to that mark is Mark Messier with 1,887. In fact, Gretzky has more assists alone — 1,963 — than Messier's total career points. It helped that during Gretzky's career, he had four seasons with 200-plus points, including 215 during the 1985-86 season — another all-time record.

UCLA basketball teams, coached by the great John Wooden, won 10 national titles in 12 seasons from 1964 to 1975, including 7 straight from 1967 to 1973. No other team has won more than two in a row. UCLA went undefeated a record 4 times, in 1964, 1967, 1972, and 1973. Pictured: Bill Walton in 1973.

Legendary driver Richard Petty finished his career with 200 NASCAR Cup wins, nearly double his next closest competitor, David Pearson (105). The King also won the NASCAR Championship seven times and won a record 27 races (10 consecutive) in the 1967 season alone. He also collected a record number of poles (127) and over 700 top-10 finishes in his 1,185 starts.

Australian tennis great Margaret Court won a record 62 Grand Slam titles, including a record 24 singles titles, 19 women's doubles titles, and a record 19 mixed doubles titles. Next closest in career Grand Slam titles is Martina Navratilova with 58. Among current players, Serena Williams is closest with 27. Court completed a career singles grand slam in 1970, winning all four major tournaments. She is just one of three women (along with Navratilova and Doris Hart) to have career Grand Slams in singles, women's doubles and mixed doubles (called the Grand Slam "boxed set").

Byron Nelson set two unbreakable marks in his incredible 1945 season.  He won 18 tournaments that year, including a remarkable 11 in a row. Next closest to the consecutive wins mark is Tiger Woods, who won seven in a row in 2006-07. Second on the list of most wins in a single season is Ben Hogan, who won 13 in 1946.

Manny Pacquiao's eight world titles in eight weight divisions is amazing considering he started fighting at 106 pounds as a 16-year-old in 1995, and he won a 154-pound title belt in November 2010. The Filipino phenom's closest competitor as a multi-division champion is Oscar De La Hoya, who has won titles in six weight classes. Interestingly enough, Pacquiao retired De La Hoya with a brutal TKO win in December 2008.
