Because everyone should take advice from professional basketball players.

Washington (CNN) – President Barack Obama’s campaign is tapping into some athletic star power in three new web videos meant to encourage sports fans to register to vote for the president.

In the latest video, titled “The Greatest” and posted Monday, basketball legends speak directly to the camera against a black backdrop and talk about the definition of “greatness.”

“It means keeping your eye on the ball and never losing sight of what’s most important,” says seven-time NBA all-star Alonso Mourning. “I believe America is still the greatest country in the world, and I am voting for President Obama.”

Current and former NBA and WNBA players Dahntay Jones, Harrison Barnes, Etan Thomas, Kym Hampton, Vince Carter, and Juwan Howard are all shown wearing Obama 2012 basketball jerseys while listing off reasons why they support the president.

“Because he knows this country succeeds when everyone gets a fair shot,” Hampton says.

“Because he will keep this country the greatest,” Carter says.
