Overlooking one of the most important points, dam stats. obviously not of much use when it's the 1st or 2nd foal, but when a mare is 3 of 4 winners with a stakes winner and offspring have several wins at 2yrs old, you better take notice regardless of trainer or sire.

good example of this happened on 5/25 in the 2nd race at BEL, Yes and Yes was out of a mare who had dropped 5 winners out of 5 starters, including a stakes winner and 3 turf winners. Would have been tough to bet on sire or trainer stats (which is probably why he went off at 35-1).
