Yes, it is not necessarily fair to write that off as jockey error. Because there was no head on view, I have no idea what was going on while not in the camera. Because the horse had seemingly settled nicely going in to the 1st turn ,I am assuming that the amount of lengths was made larger by two factors. Game On Dude was full of run all the way around the track. With the fractions set, he should have come back to the pack at some point but he did not. Secondly, did the rider of Awesome Gem ask his horse earlier but got no response? Without a head on , I do not know. This happens often enough that it does need to be considered. One reason that head on replays are so important.
When experienced and or good jockeys ride , they have a clock in there head that allows them to judge pace as well as ground needed to be made up. The fact that Game On Dude kept going was very impressive. He ran fast early, middle and late. That is saying a lot. Awesome Gem obviously ran very well also. I think that the jockey of Awesome Gem was as surprised as anyone that Dude kept going.
So if the rider on Gem moves sooner than he should because he is to far back but gets flat from the 1/8th pole home, he is considered to have rode a poor race. If he waits like he did, some will say that he waited too long. A lose, lose, scenario for the rider. And why? Because Dude ran a super race. Now if that race was run somewhere else maybe he wins and looks like a hero but it was run in California and it has favored speed on dirt forever.
I think that it needs to be accepted that Dude ran a huge race in Calif. and held on. I also think the Gem ran a very nice race and can very well turn the tables next time especially outside of Calif. To accent how well they ran, did you see Coil fold up like a cheap suit through the lane? That is because Dude broke his will to compete. If they come back with something like Coil bled and that is why he flattened out, it was Dude that made him bleed.
So if your theory pointed to Gem as the winner, your theory was very good for that race. I say that because, even though he lost , he ran big! That is all you can ever ask for is to find a horse that will run big. If you figured Dude would be in a duel or be 3 wide into the clubhouse turn , you were right. On most days that would have softened him up enough to get caught. Just not that race, in Calif., this time.
Hope that helps.
