No two fighters have conjured up more discussions, ridicule, or hype than Nick Diaz and Alistair Overeem. Both men have recently ran into trouble for testing positive for banned substances under their respective athletic commissions.

However, unlike Overeem,  Nick was caught with a substance that can’t necessarily be called a performance enhancing drug.

That drug is marijuana.

Nick Diaz was caught with cannabis metabolites in his system following his fight against Carlos Condit at UFC 143 and now faces a flood of legal troubles that will keep him sidelined, probably for the rest of the year.

This comes as an extreme disappointment as Nick has put on two entertaining fights since he’s come back to the UFC fold, along with more than memorable moments outside of the Octagon; such as his failure to show-up to two separate press conferences that cost him a title shot against Georges St-Pierre at UFC 137 and the respect of UFC brass.

Nick is a necessity to this sport though. Not because the UFC would go broke without him. They would not, but instead of what he brings to the table.

First off, even though he is probably the most camera shy fighter in the UFC, he markets fights effortlessly because of his brash attitude and talented fight game.

His trash talk is real unlike that of Chael Sonnen’s. Nick legitimately means what he says and plans on backing it up. He never backs down from a fight and has turned the soft spoken champion, Georges St-Pierre, into a hate filled monster whose only job is to find a way to fight Diaz and beat him senseless.

Second, Nick brings a different kind of game to the welterweight division. He is not a wrestler, but he’s good on the ground. He’s not exactly a knockout artist, but he can batter his opponents and also take a shot with his granite jaw. He also has some of the best conditioning in the sport due to his training routine and frequent participation in triathlons. These factors all culminate in a fighter that fights until the fight is over and doesn’t sacrifice an inch to his opponent.

If he were to come back, a fight with either Jon Fitch, or the winner of Johny Hendricks and Josh Koscheck would suit Diaz. He needs to be fighting top competition to make him care about beating down his opponent that much more.

The idea of Diaz retiring would be the stupidest move he could make as a loss to Carlos Condit doesn’t exactly mean that you’re at the bottom of the totem pole.

This man needs to be fighting, every weekend if such a thing were possible, forever. He is an extremely talented and entertaining fighter who provokes no worry in the hearts of fans, in that we know what kind of fight we are about to watch, when he starts to walk towards the Octagon with his Metal Mulisha apparel and trademark Stockton snarl.
