the harder you work,the harder it is to surrender. - Vince Lombardi

If you can accept losing, you can't win.

They call it coaching, but it is teaching. You do not just tell them it is so, but you show them the reasons why it is so and you repeat and repeat until they are convinced, until they know.

Tackling is easier to teach and keep tuned than blocking simply because it is more natural. If a man is running down the street with everything you own, you won't let him get away. That's tackling.
