Below is an example highlight video that I time to time create for some of my players. I generally use iMovie and have found that to be a terrific program. However the process of clipping, editing, adding effects, adding music, etc. is very tedious. The reason I do these sorts of things for my players is because 1.) I believe small things make a big difference and 2.) it helps a player's confidence and visualization even if just a little. I believe if a player sees his or her coach going the extra mile to do a "little thing" like this then they will sacrifice that little bit more for the coach and for the team through the process of improving. Basically you want your players to be more dedicated and sacrifice more time? Then set the example for them. It's a two way street.
Please feel free to provide suggestions or comments on how to make future highlight tapes better.
