Can someone explain the Colonel John silliness to me?

santa anita could switch back to dirt..........although the CUSION seams to be more comparable to dirt than POLY.

I think the real silliness is making Big Brown the Derby favorite off of one race.....by the way, Colonel John is my top pick at this time. Process of elimination, all the other possible favorites got holes in them too. At least Colonel John has run consistent, albeit on a non-dirt surface.

I thought he had some dirt runs at two?
