Daniel and Henrik Sedin
At this point in their lives, it's likely that Vancouver Canucks forwards and identical twin brothers Daniel and Henrik Sedin are accustomed to being mistaken for one another ? just not during games. On Jan. 13, 2014, Daniel was called for a holding penalty against Los Angeles Kings defenseman Drew Doughty. During the delay before the whistle, several players congregated near the corner boards, including Daniel's twin brother Henrik. Apparently the cluster of players resulted in some confusion, which led to Henrik being mistakenly directed by the officials to the penalty box to serve an infraction he didn't commit. (WATCH VIDEO) In 1999, the Sedin twins were regarded as two of the top prospects in the league and requested to play together, which led the Canucks to make a series of trades to grab them with the second and third overall picks. They both won gold with Team Sweden at the Turin Olympics in 2006.

Rex and Rob Ryan
Born five minutes apart, Rex and Rob Ryan are as close as can be. The two cut their teeth together as defensive position coaches in Arizona before moving on to defensive coordinator positions, and during the season, the two exchange phone calls almost daily. But all that falls to the wayside on game day. Head coach Rex's New York Jets are 3-0 against teams with Rob as the defensive coordinator. Rob's Cleveland Browns lost 26-20 in overtime on Nov. 14, 2010, his Dallas Cowboys lost 27-24 on Sept. 11, 2011, and his New Orleans Saints lost 26-20 on Nov. 3, 2013.

Ronde and Tiki Barber

Ronde is the only NFL player with 25 or more sacks and 40 or more interceptions. In 2006, Tiki became just the third NFL running back in history to rush for 10,000 and rack up 5,000 receiving yards.

Robin and Brook Lopez
Twin 7-footers, who dominated at Stanford, Brooke and Robin Lopez are pretty distinguishable in game and looks. Brooke has a near buzz-cut, was selected 10th overall by the Nets and averages close to 20 points per game over the past few seasons. Robin has a scraggly afro, was selected 15th overall by the Phoenix Suns and isn't a prominent scorer and rebounder like his brother.
