Granted, this is after the fact, but I found a set of Rags for the Derby and noticed two very big differences and a few similiarites that made me scratch my head.
Note that this not meant to support and or fault either.

1) The Cliff's Edge was a complete toss on Rag based on the fact that he had yet to break through his 2 yr. old best prior to exploding to a 5 point new top in the BG.

2) Smarty Jones appeared to be a different horse as well. The most interesting thing was Rag had an off race prior to the big move in the Rebel. He was still 0-2 , but had not thrown in 3 straight efforts and looked much more bettable. For CtC and others less pig-headed than me, he was bettable in any case.

3) Lion Heart was the same on both.

Thanks.
