Detroit Lions legendary running back Barry Sanders turns 47 today.

During his time in the league, he racked up an NFL-record 14 consecutive 100-yard rushing games and the most 1,500-yard seasons (5).

In honor of his birthday -- and his records that won't be broken anytime soon -- we look at the sports marks that are least likely to fall, and which active athletes are closest to breaking them:

Barry Sanders' 14 consecutive 100-yard rushing games

Active leader: Jeremy Hill, 3 consecutive games

Sanders was the third overall pick in the 1989 NFL draft. He rushed for over 1,000 yards in each of the 10 seasons he played. If Cincinnati Bengals RB Jeremy Hill wants to break Sanders' record, he'll have to be stellar in the next 11 games. That would mean rushing for 100-plus yards in every game until Dec. 6. The last player to come close to breaking the record was Chris Johnson in 2010 (12-game streak).

Barry Sanders' five 1,500-yard seasons

Active leader: Adrian Peterson, 2 seasons

Sanders also holds the NFL record for most seasons with 1,500 or more rushing yards. Adrian Peterson has had two seasons with 1,500 yards, and he has already played in the NFL for eight seasons. To catch up to Barry, the 30-year-old will have to be in tiptop shape for the next three seasons.

Kareem Abdul-Jabbar's 38,387 career points

Active leader: Kobe Bryant, 32,482 career points

Abdul-Jabbar spent his stellar career with the Milwaukee Bucks and Los Angeles Lakers. Bryant could break his record, but he would have to stay healthy and score 25 points per game in at least 237 games. That's almost three straight seasons for a player about to enter his 20th season in the league.

Wayne Gretzky's 2,857 career points

Active leader: Jaromir Jagr, 1,802 career points

When he retired in 1999, The Great One held more than 60 NHL career records and many of them aren't going anywhere anytime soon, if ever. No player since 1996 has reached 140 points in one season. A player could put up 140 for 20 straight seasons and STILL not reach Gretzky.

Joe DiMaggio's 56-game hit streak

Active leader: Troy Tulowitzki, 21-game streak

DiMaggio's streak began on May 15, 1941 and ended July 17. During his streak, Joltin' Joe was 91-for-223 (.408) with 15 home runs and 55 RBIs. To top DiMaggio, Tulowitzki needs a hit in his next 36 games -- that's every game until Aug. 25.

Brett Favre's 321 consecutive starts

Active leader: Eli Manning, 178 consecutive starts

Favre not only holds the record for most consecutive starts but also for most pass yards, most pass completions and most starts, among others. Eli Manning can make Favre's record fall, but he can't miss a game for the next nine seasons. He's 34.

Michael Jordan's 866 consecutive games with 10 points or more

Active leader: LeBron James, 641 consecutive games

Michael Jordan also holds the record for highest career regular-season scoring average and highest career playoff scoring average. If LeBron wants to top MJ, he'll have to score double-digits in every game for the next three seasons, thus not getting hurt early in any game.

Jerry Rice's 1,549 career receptions

Active leader: Reggie Wayne, 1,070 career receptions

Rice is arguably the greatest wide receiver to ever play the game. He spent 20 years in the NFL with the San Francisco 49ers, Oakland Raiders and Seattle Seahawks. If Wayne averages 80 receptions per season -- he averages 76 currently -- for the next six seasons, Rice's record will fall. But what are the chances the 36-year-old has six more seasons?

Cal Ripken Jr.'s 2,632 consecutive games played

Active leader: Kendrys Morales, 123 games

The average MLB season is currently 162 games, which means Ripken played over 16 seasons without missing a beat. If Kendrys Morales wants to rewrite history, he'll have to play in every game until he's 47 years old. That's over 15 years away.

Emmitt Smith's 18,355 rushing yards

Active leader: Steven Jackson, 11,388 rushing yards

Emmitt accumulated a ridiculous number of rushing yards with the Dallas Cowboys and Arizona Cardinals during his 15 seasons in the league. In order for Jackson, who is in his 12th season, to break his record, he would have to have an average of 4.2 yards per carry on the next 1,659 carries. Based on his career averages, that would take him 95 games or about six seasons.

UCLA men's basketball team's 88-game winning streak

Active leader: Duke Blue Devils, 6 games

John Wooden and UCLA started the 1970-71 season on a winning streak and didn't lose a game until Jan. 19, 1974. Duke will have to string together at least two perfect seasons in a row to get there. There has not been a perfect season in college basketball in 39 years.

Connecticut women's basketball team's 90-game winning streak

Active leader: UConn Huskies, 37 games

UConn has been a juggernaut in Division I women's basketball for some time. They didn't lose a game from the start of the 2008-09 season until Dec. 30, 2010. The Huskies, fresh off their third straight national title, are attempting to break their own record. With back-to-back perfect seasons, they can do just that. That's not too much to ask, right?

Cy Young's 511 career wins

Active leader: Tim Hudson, 219 career wins

Young pitched for five different teams throughout his 21-year career. He has held his record for over a century and has more than twice as many wins as the closest active pitcher. Tim Hudson, a 16-year vet, averages 13 wins per season. At that rate, it would take him around 14 seasons to come anywhere close to Young. He would be 53 by then.
