I know it's hard to tell without seeing the play, but here's what happened:
On a kickoff return, the runner had a good head of steam and approached 3 defenders. About a yard from contact, he leaped into the group of defenders. He didn't extend his foot or knee in front of him. It looked more like a Packer player doing the Lambeau leap than Edwin Moses running the hurdles.
We didn't throw a flag. What do you think?
Never mind, just read the definition. Player did not have one or both feet or knees extended, so it sounds like we got it right.
