Proof of BC "Golden Rail"?

[hockey2315]

After Round Pond's race today I got to thinking about the BC winners on dirt this year and how they've performed after the BC:

Dreaming of Anna- Beaten on both dirt and turf- hasn't looked nearly as good as last year

Street Sense- Has yet to race again- mixed reports of his current condition

Thor's Echo- Won at LRL and then lost badly in Dubai if I'm not mistaken

Round Pond- Didn't run at all today.

Invasor- Great race in the Donn. . . Don't think he had a rail trip in the Derby.

Now obviously, there are other factors that must be taken into consideration. And I also can't remember at the moment which horses trips could actually be considered aided by the "golden rail."

But this seems interesting and worth noting to me. . .

Any opinions?
