Hi football officiating experts.

I am doing a ten minute presentation on a sporting topic of my choice and I have chosen officiating football - namely the NFL.

I was wondering if anyone here could please provide me with links to the following pieces. Thanks ahead of time, any help is much appreciated. I figured many users of this board would know some good ones off hand.

1 - Bios/pictures of NFL referees. I want to show how they are part-timers and show some pictures and full-time occupations of some of the NFL officials.

2 - Basic positioning manual - where the 7 officials set up on specific plays.

3 - Overview of penalties & hand signals.

4 - Website showing clips of penalties and calls being made by referees.

Like I said, any help would be greatly appreciated. Thanks so much.
