He wasn’t punished for his activities, and therefore was never proven to be at fault. (He was never charged with any crimes, so he couldn’t have been found guilty.)
But the reality remains - he is aPR nightmare. I mean, OJ was acquitted, too. Has it helped his public image?
All that said, I wonder why the Sox are actually concerned with their image right now. They’ve turned off so many fans, Bauer could win a second Cy Young and half of New England might not notice…
