For a generation that gets most of its information off a computer screen (be it Facebook, Instagram, YouTube, Twitter or what have you), an athlete has to be very careful about the public/private aspect of that. Be careful not to be overly critical, be careful with use of language, and understand the whole world is watching.

I love the values football can teach. It gives young people a sense of how to defer present gratification for future success, it teaches self-discipline, it teaches teamwork, it gives them a bonding experience that can be hard to find somewhere else, it teaches the ability to process large amounts of information and apply it in real time.

As I write in my book, there is a misnomer that destroying another person's position is an effective and practical way to negotiate.

The NFL today has bigger, stronger, bodies than ever, moving faster than ever, hitting a stationary object harder than ever before - so the physics of the hit have changed.

It's learning how to negotiate to keep both sides happy - whether it's for a multi-million dollar contract or just which show to watch on TV, that determines the quality and enjoyment of our lives.

When it came to football there was a certain age where I realized that my future in football was being a grease spot on the side of some bigger player.
