Is Curlin being overrated by the margins over nothing horses?

Nothing against Curlin, as I think he's a quality horse (and less likely to be "aided" than others that won everything yesterday for Assman) but there's a reason his horses never run big on big days...

Detention barns.

Not trying to be a smartass, but which high caliber trainers have NEVER cheated, ever?? My guess is some have never been caught. I know Pletcher, Asmussen, O'Neill have all cheated so that's a large chunk of the Derby field right there. Which ones NEVER cheat??
