Even though I don't "get it," I follow your rationale, Chris. At some point I'd be rooting against one of my favorite players and that doesn't feel good.
For instance: Courier is serving to go up 2-1 sets and a break on McEnroe. Do I want him to choke??? Yeah, but that feels s**tty, especially if #1 is on the line; i.e., beating McEnroe would make Courier #1 over Sampras. No thanks.
I think that's what falcon was saying, too.
With Nole-Rafa, it was easy for me to enjoy the tennis and root for both players because I didn't have a dog in that fight. Even though it's the best show currently on tour, Nole-Rafa is not a dream final to me.
