The slightly eccentric KSI is a British YouTube "influencer" and musician. He has over 21 million followers, of which 2.4 million have tuned in to his review of "AFL" football where he rates it a 9.6 out of 10 for toughness. His video clip focuses on 10 minutes worth of some of the toughest tackles and hits of recent years. The massive following of the clip has introduced the game to an even wider audience, mainly across Britain and Europe - something invaluable for the game, which is why the risque (though funny) clip is worth watching.
WARNING: This clip does contain occasional profane language, some racial overtones (though contextually relevant) and some extreme overacting...but, its worth it.
