From my point of view.
It's because he looks like an early season juvenile with flat speed and experience that would not be able to go the gallop when the big day comes.
In this particular case, i'd say even more so as he's had 2 fairly steadily run races to aim at.
They used to do not bad, but these days they tend to get beat up by the French breds.
It's unlikely on the new course with so few hurdles in the last mile that they won't get racing early, and this usually finds these types out.
So basically. As De Niro or Depp would say
"Forget about it".
