So what's the value in knowing you need to come off the ground. This is already happening with video in games.
As the recent NFLPA have said "We don't need to know what's happened as much as we need to know what to do with next?" Adidas had this product out many many years ago and shelved it as people didn't see the value in being told they got hit hard. They want to know the effects and how to manage it... Do they do this? Not from what I can see but hopefully they may be able to?
