So here's what I think happened:
Rusty Hardin (Wesleyan '65) took a look at the case. He realized that his client was an unlikable bully who couldn't keep his yap shut, operating in a climate that was disinclined to be sympathetic to those accused of using steroids. He saw that the prosecution had handled its prosecution of Barry Bonds with all the delicacy of Paula Deen taking a frozen ham to the side of her head. He saw that the government's case, regardless of whether or not his client had in fact jammed his ass full of enough monkey hormones to make him climb the Empire State Building clutching Naomi Watts in one meaty paw, rested on the testimony of a dyed-in-the-wool scumbag. And he did a little math - they do teach math at Wesleyan, when no one is looking - and did a rough estimate of how long this case could run, and how many billable hours he could get out of it.
Then, in my imagination, Rusty Hardin did his best maniacal laugh, twirled his imaginary mustachios, and tied an innocent woman to a set of disused railroad tracks. Because that's what Republic Serial Villains, like Rusty Hardin, do.
To be fair, nobody really expected Clemens to be found guilty, not when the government's entire case rested on Brian McNamee, and the public remained convinced Clemens was on trial for using steroids. (He wasn't. He was on trial for perjury, which is kind of serious, and the sort of thing you'd hope they'd actually prosecute, otherwise that whole "trial by jury" thing goes out the window. But I digress.) But Clemens had already had his name dragged through the mud, the public was sick of it, and it became fashionable to bitch about what a waste of time and money the whole thing was.
The real test, of course, will come when it's Clemens' turn on the Hall of Fame ballot. Remember, he wasn't found not guilty of using steroids. He was found not guilty of committing perjury. And the gatekeepers of the Hall of Fame tend to frown upon steroid users and suspected steroid users, even ones who never failed a test or were mentioned in the Mitchell Report or got put on trial for perjury.
There's a hell of a lot more evidence to suggest Clemens did PEDs than there is against Jeff Bagwell. If Clemens gets in - if Clemens gets close - while Bagwell and McGwire and Sosa are locked out, then all hell will break loose.
Then again, maybe it won't. Maybe the weary acceptance of Clemens' greatness will open the door for those other guys.
And if it doesn't, I'm sure Rusty Hardin would be happy to advocate on their behalf.
