I was all about Dr. Brown, partly because ours was a rock star. For the other reason, it's hard to get into why without specifics. But suffice to say, with a Dr. Racheter played as many college students tend to play witnesses (inappropriately altering facts, denying affidavit content, and generally becoming partisan), it was real easy to have Brown as the only credible expert in the round.
My team's 4th round opponent that year handed that to me (the Racheter crosser) on a silver platter. It's still my favorite round, to this day.
