There are some scenes in Facing the Giants that are VERY motivational!
At practice I plan to show the one where the coach makes Brock do the "Death Crawl". It is about 5 min and it shows how self negativity can effect someone and the rest of the team. It shows what someone can achieve when they have HEART. It also shows how people will take notice and respect the efforts someone when they are truely giving everything they got and how effort like that can inspire others!!
This move has bad acting but SO MANY GREAT MESSAGES!!
You can also find these clips online.
I know youtube.com has them. Search "Facing the Giants"! There are a few clips on there where people are spoofing the movie look through a few and you will find what you are looking for and can show the clips for free instead of buying the movie!!
