It is a fantastic resource for coaches and will aid you in building sessions that are both effective and focused on skills and development.
The site covers all levels of the game from mini/mod right up to international level coaching with mini games and core skill sessions to suite.
There is also commentary on most drills outlining the goal of each drill, explaining the what is happening during the drill, and finally giving you pointers with regards to what to concentrate on when coaching the session.
I could go on all day about how highly i rate this fantastic resource but the best thing i can do is provide you with the Link and let you have a look yourselves.
Just register and away you go.
Cheers
