Luke Kuechly announced his retirement at the age of 28. He becomes the latest notable player to retire while still young, joining Andrew Luck, Gronk, Calvin Johnson and others. I think this will become an even bigger trend as more research and information comes out about CTE and head injuries. Some believe people will eventually stop playing football altogether. While that could happen, I don't see it. Football is to much a part of our culture. Plus, more kids seem to be playing flag football and then moving to tackle football as they get a little older. I think it's more likely that players who make it to the NFL will play through their first couple of contracts and then retire early while still relatively healthy.
