Here's the important part, as transcribed by O'Brien (it comes at around 40:30):
Lopez was then asked flatly if players were looking at steroids as an option and using them.
“Uh, yes,” he said. “In my opinion, yes…. I mean, how can I explain this? It’s like if you’re going to race cars, if you’re going to race a car and some people are using nitro in the fuel [Lopez laughed], and you see them winning all the time, and you’re using regular gas – you know what? If they’re using nitro and they’ve been winning, well, I’d be stupid enough not to use nitro, too.”
Look, everyone's innocent until proven guilty. But people have been whispering about Javy since his career year in 2003, when he hit 43 home runs in just 129 games and batted .328/.378/.687. I'm not trying to indict him on circumstantial evidence... but it's not hard to see what he's saying. He's saying that when everyone's using, you have to use too. And it doesn't seem like a stretch to imagine that he's actually talking about himself.
