Don\'t want to rain on your parade, Alm, but there is another factor nobody has mentioned so far about Big Brown -- to wit, the horse has yet to react!
In my book, I never give a horse a reaction until he has given me a reaction. We simply have no idea what a horse is until he reacts. I do not want to scare people, but what happens if Big Brown steps forward in the Kentucky Derby? I know it sounds crazy to say a young 3 year old can run a minus X and then actually come back in his next start and run a minus 2X, but why not? If you saw a three year old who ran a 20-17-14 in its first three races, what would you expect him to run in his fourth race? You would have to give him a significant percentage chance of moving forward. Well, the only difference with Big Brown is that his three races are so huge you have to think they must take a toll. But, without knowing what the horse\'s baseline is, how can you judge that? Remember, this is a 3 year old, early in the season, making only his third start of the year, with good rest into the race. All conditions militate more towards moving forward than towards going backward. While I would have to think that the chances of him moving forward are not high, I do not think they can be reasonably said to be non-existent.
Again, I am not excited about betting a favorite, but I would have to think that this horse could end up being very hard to go against.
