Choosing sides: Do you believe Roger Clemens or Brian McNamee?

For anyone who missed Roger Clemens' interview on 60 Minutes last night, here's a one-word summary: robotic.

Clemens, unsurprisingly, took the deny, deny, deny approach, explaining multiple times in his Texas accent that "it never happened."

He was also critical of those who've assumed the worst about him, arguing that his 20-plus years of Major League service should give him the benefit of the doubt.

"It's hogwash for people to even assume this," Clemens said. "Twenty-four, 25 years, Mike. You'd think I'd get an inch of respect. An inch."

While he's right that citizens are innocent until proven guilty in the court of law, things tend to operate a little differently in the court of public opinion. Especially when it comes to steroid usage.

One of two people here is lying: either Brian McNamee is fabricating this whole thing and Clemens is just trying to clear his name, or McNamee is telling the truth and Clemens is attempting to orchestrate a massive cover-up.

The one factor in Clemens' favor is there may never be physical evidence to substantiate McNamee's claims. Just because you said you did something, doesn't necessarily mean you did. If you can't provide tangible proof, this may become a word versus word situation.

But let's take a closer look at McNamee. Here is a guy who has worked with Clemens for 10 years, befriended him, staked his entire reputation as a physical trainer on the Rocket's success. What does McNamee stand to gain by lying about injecting Clemens with steroids? And after denying involvement in steroids after the Grimsley report was leaked, why would McNamee change course when testifying to Senator Mitchell?

If he was telling the truth the first time, wouldn't he stick with his story?

Furthermore, if Andy Pettite -- who is among Clemens' closest friends and trained with McNamee alongside Clemens -- admits to having used Human Growth Hormone, what does that say for Clemens? I don't know about you, but I find it hard to believe when Clemens says he "had no idea about" what Pettite was doing.

I could go on, but what's the point? All of this and much, much more will come out in Clemens' newly-filed defamation suit against McNamee, and when the two men testify before Congress on January 16.
