I'm trying to recall the name of a book. No idea about the publication date, but I guess I read it roughly 10 years ago. It was a young adult sci-fi, the premise of which was that teens (no one older, maybe something about adult brains being too developed) could "jump" to another planet using technology. The group of teens that jumped were doing recon on the new planet, I think trying to infiltrate the base of another race, and there was a game of football involved somehow.
The book was Yanked! (David Brin's Out of Time) by Nancy Kress.
It's 2345. THE FUTURE NEEDS HEROES! They must reach back in time to find them. WHAT IF THEY COME FOR YOU? In 2345 there is no war, no pollution, no disease, no crime--but utopia has a price...
