Dutrow concerned about Harlem Rocker

[ateamstupid]

I don't think anybody knows anything about Harlem Rocker, even Pletcher. Dutrow is concerned because "Todd's white horse" COULD end up being very good, whereas everyone else in the Preakness has proven to be inferior to Big Brown. He also could end up just being an above average miler, but he's the only unknown in the field, hence the concern.
