Maybe some day I'll be able to have fond feelings of Brent. Right now, he is still DTM (dead to me).
When he was a Packer, and therefore a "God" in Packer fans Green and Gold colored glasses, I would tell some of the stories about what a poor team player he was, how he could be somewhat of a jerk to fans, and other "lowly" Packer employees, and how he hated having to hang out with his team mates (he said he had nothing in common with them). During those times, many here refused to believe me.
After telling you my perspective, I can honestly say that I never, ever heard any substantiated rumors about him "catting around". Now maybe you are talking in the past 3 years (after all, since then I no longer have the inside info), or longer than 12 years ago (before my "inside guy" was employed there), so I am not doubting you. But if it was from 1998-2007, if there were rumors, I can say I don't think they are true.
