The NFL actually does employ great people. Though it is hard to believe, especially after the horrible behavior of (now, former) star players Ray Rice and Adrian Peterson, the NFL employs thousands of other people who are consistently amazing. Meet exhibit A: Ma'ake Kemoeatu, who just retired from the NFL to save his younger brothers' life.

Before Kemoeatu became a nose tackle for the Baltimore Ravens, he became the oldest of seven children. One of his younger brothers, Chris, has had kidney problems since he was in the eighth grade. Still, against the signs his body was giving him, he played football until things got worse. Pictured below:

Chris was able to make it through his college career Utah and move on to play with the Pittsburgh Steelers before he finally could not take the pain. In 2011, Chris retired from football, and in 2012 his older brother Ma'ake did the same.

A year later, things got much worse as Chris was diagnosed with advanced kidney disease and was going to need a transplant to survive. Immediatley, Ma'ake stepped in to help. "If my brother or any of my siblings needed blood, they have to have my blood," Ma'ake told reporters at a press conference in Maryland. He added, "If any of my siblings needed a kidney, it would have to be my kidney."

Though their dad wanted to do it, Ma'ake would not have it any other way. Later that year, doctors discovered that Chris also needed heart surgery but in August, he was able to finally get his brothers' kidney.

Dr. Stephen Bartlett performed the transplant and said, "It was one-and-a-half times bigger than any other kidney I had ever seen in my life." Now, both brothers are doing fine and though neither of them are planning to return to the league, they are thankful to be alive.

Hopefully, as the NFL figures out what to do with the current bad press they are dealing with, they choose to highlight more players who are remarkable like Ma'ake Kemoeatu.
