I recently discovered that the French Rugby Union has it’s own video sharing account at Dailymotion. In addition to interviews and clips from big matches, they’ve got some great drill videos that I’ve only just started going through. Have a look at this clip on the tackle contest, and note that there are plenty more down the right hand side (… and they’re even MORE useful if your French is better than mine!)
