Hmm ... When I lived in London (roughly GCSE age or so), PE rotated sports - we did baseball, cricket, football, rugby, badminton, track & field, swimming, netball, volleyball, basketball, and hockey. When I lived near Sydney (the rest of my educational years), we did basketball. Nothing but goddamn basketball.
I HATE basketball with a passion now. I hate the feel of the ball, I hate the obnoxious noise of bouncing and sneakers squeaking, I hate dickheads trying to slam dunk, I hate the morons who acted like tough-as-nails gangstas - when they were playing a fucking NON-CONTACT sport. It was just a lot of upper-middle class white Australians posing. Shiiiit.
But srsly, give the kids a wide variety of sports to try. Students will, like me, get the shits if you just play the same damned sports all the damned time. PE is important; teenagers need to practice with their bodies. One of the reasons adults can't run and jump and be as nimble as when they were kids is because their brain hasn't done it *since* they were kids - your body has changed size and shape, and your brain, put simply, doesn't know how to control it anymore.
