UFC middleweight champion Chris Weidman doesn’t have any answers to the questions about which Anderson Silva will show up to Las Vegas’ MGM Grand Garden Arena Saturday night in UFC 168’s pay-per-view headliner.

Will it be the focused Silva with incredibly accurate, one-shot power in his strikes? Or will it be the Silva who goofs around in the cage, taunting and publicly humiliating his foe in front of thousands in attendance and millions more watching at home?

To the reigning 185-pound champion, it doesn’t matter which version of “The Spider” walks into the arguably the biggest UFC fight of the year. Weidman is focused purely on which version of himself shows up.

“Some of the questions I hear often are, ‘What do I think Anderson Silva’s going to do in this fight?’ ‘Do I think Anderson Silva is going to be playing around in this fight?’ ‘What do I expect from him?’” Weidman said today. “I don’t expect anything. I don’t really care, I’m just going in there to fight my fight, so when people ask me those questions, it’s the first time I really think about it. I don’t think about what he’s going to be doing.”

If you think Weidman may be bluffing with his nonchalant attitude toward his challenger’s strategy, simply take a look at the first fight between the two for evidence. Silva (33-5 MMA, 16-1 UFC) was undefeated in the UFC at that time, and his aura of invincibility was at its peak. But that didn’t stop Weidman (10-0 MMA, 6-0 UFC) from showing complete disregard for Silva’s antics as he connected with the fight-ending blow.

While most fighters would look at a performance like that as one to replicate, Weidman is a perfectionist and feels quite the opposite. The 28-year-old sees many flaws in his showing at UFC 162, and with momentum behind him going into this weekend’s rematch, he expects the fight to play out much differently.

“I’m not a big fan of the first fight because I don’t think I looked that good, to be honest with you,” Weidman said. “I know I can be a lot better.”

Such harsh self-assessments are one reason Weidman is the UFC’s lone undefeated male champion, and he wants to keep it that way.

“I was coming off that year layoff, had two surgeries, so I felt a little rusty in there,” Weidman said of their first meeting. “There are some things I didn’t do. I’m very critical of myself, so there are a lot of things I assume I could have done differently.”
