It\'s interesting that the examples you cite to make the case that the Preakness is formful are all recent. It\'s kind of like the debate over global warming...we know for a fact that things are heating up, but not why this is the case...we cite the temperature change, but ignore that it\'s happened before.
In fact, there was an era when the Preakness was not formful. There are examples of Preakness winners who flamed out as Derby choices. I\'m not sure the sample is large enough to draw any conclusions, regardless of how far back you go.
This still turns into a specific race on a specific day with specific horses, which will never repeat itself. I don\'t think you can make or break the filly\'s chances based upon previous history.
However, you can decide to bet her or against her, knowing that she\'s 50% to run well enough to win, or lose. It\'s about the value you are looking for.
If you want to make that play, God bless you and good luck. In this case, I prefer to bet a trainer, a guy who I don\'t think is a consummate egotist and who I don\'t think would be rolling his horse back into this race just for the opportunity to travel to the craphole Pimlico racecourse. I think he\'s a guy who thinks he has a real shot...Larry Jones. I go with Freisan Fire and a Larry Jones Black Eyed Susan-Preakness double.
