YEAH
I think juice is supposed to get horses to win races; simple as that. Running faster, significantly or otherwise, is just a subset of that. But horses that don't want to win races, like Jelly Roll, are nonetheless supposed to be improved by juice. And the IMMEDIATE improvement of precisely these types of horses would be an indication of juicing. However, Jelly Roll ran twice under Wolfson before turning in, CLEARLY, her best effort to date last out. An effort that stamped her as the horse to beat today.
Then again, maybe he put her on the CYCLE juice rather than the IMMEDIATE ACTION juice.
Anything is possible.
Next up: he gets a win for Onoitsmymotherinlaw
