Although Georges St-Pierre’s decision-making ultimately got him a shot at the belt, Nick Diaz still isn’t convinced the UFC welterweight champion is making the best career moves.

St-Pierre (23-2 MMA, 17-2 UFC) and Diaz (26-8 MMA, 7-5 UFC) meet next week in UFC 158’s pay-per-view headliner. The March 16 event, which takes place at Montreal’s Bell Centre, will conclude a beef that began in June 2011, when officials first announced their plans for a St-Pierre vs. Diaz bout.

However, since then, St-Pierre’s injuries, as well as Diaz’s press-conference absences and drug suspension, have delayed the booking. But a bout nearly two years in the making is now right around the corner.

However, in a pre-fight interview that the UFC conducted, Diaz said he is surprised St-Pierre hasn’t been campaigning for another fight – one with middleweight champion and pound-for-pound kingpin Anderson Silva (33-4 MMA, 16-0 UFC).

“I started (competing at) like from 16, 17, 18, 19, 20 (years old),” Diaz said. “By 23, I’m fighting No. 1 people in the world. I will tell you right now I’ll fight the No. 1 guy in the world. I’ve always said, that I want to fight the No. 1 fighter.

“Georges has never said that. That’s the only thing I’ve ever said negative about Georges, that if I were in his place, I’d be asking for the Anderson Silva fight. I wouldn’t let that blow away. That’s crazy.”

A victory over Diaz, though, could set up such a scenario. As MMAjunkie.com (www.mmajunkie.com) recently reported, UFC President Dana White has promised either a St-Pierre vs. Silva or Jon Jones vs. Silva super fight by year’s end.

Of course, should Diaz pull off the upset next week – and given his willingness to campaign for the big fights he wants – he could conceivably slide into one of the slots.
