Road Toad is correct when he says NOBODY can really say who is and or was the best filly or mare of all time. Just like any other sport played with humans - Basketball, Baseball, Football etc..., there is always an arguement of who is the best who was the best of ALL TIME. Personal Ensign is certainly in the top 5 of all time on everybody's list. Even trying to compare Rachel to Zenyatta is difficult because of them being different from 4 yr old versus 6 yr old, Dirt track preference versus Synthetic track preference, East Coast based versus Southern California based and the actual arguement has both sides to the story and will NEVER be 100 percent decided because they will NEVER meet at a track on a surface that both sides will agree is fair to both parties. First to admit that if they do meet at Churchill Downs the first week of November this year in the Classic and Zenyatta wins that race, then I will be the first post that Zenyatta is the best of the two. But will also be the first to admit that if Rachel wins and Zenyatta does not run very well that Zenyatta was up against it because of traveling East and running on a surface that is not her specialty. Ask 100 professional in the know horsemen to evaluate the works of both Rachel and Zenyatta from January 1 2009 to today and you may get 51 to agree with one and 49 to agree with the other. I think Zenyatta is tailing off her form and is not as good as she was last year, as MOST ALL 6 year olds do which will only add to the speculation if Rachel beats her as well. Most likely Z will race 2 more times before the Classic and don't be suprised if she continues to not show the form as last year but there is a real possibility of her getting beat. I see the trainers that were ducking her last year as taking more of a shot at her this year with her decreased in form. She wins that race Saturday by 3 easy lengths last year and was all out to win by a half a length. I know if I saw what I did and had a Grade 1 Mare, I would take a shot at her now and would have been ducking her last year.
