I always have reservations whenever Sports Illustrated or another outlet begins to over hype a high school athlete. There’s the quest to find the next big star, and being anointed can put a lot of pressure on a young kid.

However, it’s hard to argue with Sports Illustrated’s decision to put Jabari Parker on the cover this week. Living in Chicago, we know all about the Simeon High School basketball star. He’s that good. Will he be as good as LeBron James? Time will tell, but you’ll likely be hearing about him for a long time.

Also he has an interesting story. He isn’t your typical high school superstar looking to take the quickest path to the pros. Here’s a preview:

Jabari Parker, a junior at Simeon Career Academy in Chicago, is the best high school basketball player since LeBron James, but there’s something more important to him than hoops stardom: his faith. Parker—who was the 2011 USA Basketballathlete of the year and is being recruited by all the top college programs including Kentucky, Kansas and Duke—is a devout Mormon. After his freshman year in college, when top players will head to the NBA draft, Jabari will have to decide whether he will declare for the draft or—like thousands of other Mormon men who turn 19—embark on a two-year mission to spread the faith in the U.S. or a foreign country.

Parker appears on the cover of the May 21, 2012, issue of Sports Illustrated, on newsstands now. Parker is the first high school athlete on the cover since Bryce Harper appeared on the June 8, 2009 cover.

Jabari wakes up each morning at five and says a prayer, and three days a week, he is at Bible study by 5:30. Parker also accompanies a Bishop of his church on visits to the sick, the poor and the elderly—an assignment designed to teach young men the importance of service and self-sacrifice. Parker tells contributing writer Jeff Benedict, “I realize why I’m in the position I’m in right now. It’s not because of me. It’s because of God.”

He knows his decision will be difficult. His brother Christian, who has already served a mission, has told Jabari that it was the best thing he’s ever done. Jabari says, “When he came home from his mission, we talked a lot about it. I want to go. But I have doubts. The NBA is the biggest dream of basketball players, and I’m not different.”

Also in this edition, Chris Ballard profiles Tim Duncan.

Tim Duncan is the most successful player of his generation, maybe even its best. In the 15 years since Duncan was drafted, no other team in the four major pro sports has had a better winning percentage than the Spurs. Now Duncan is the foundation of yet another Spurs team that could win it all. So why haven’t the masses fallen for him? Senior writer Chris Ballard breaks down the 21 reasons why Duncan, compared with his peers, remains practically anonymous (page 36).

Duncan said, “Winning should be the only thing that matters. I can’t manipulate how people see me. I could be more accessible and be the darling of everybody. I could open up my life and get more endorsements and be out there and be a fan favorite. But why would that help?”
