In today's Post, they canvas views from a variety of experts on the question of whether or not Dawn Approach will stay. I particularly enjoyed this from Henry Beeby: "I think he will stay for two reasons: first, I don't think Jim Bolger would run him if he couldn't, and second, I think he will because he just oozes class, and class will out."
On the first point, presumably no trainer would run a colt in these circumstances if he couldn't stay but that's not the same thing at all as saying that Bolger knows he will stay. Bolger knows no such thing. And on the second point, the logic of this argument is that virtually every above-average Guineas winner to run in the Derby would have won it. That is just not true. Class and stamina are totally different things.
The Derby is run over the stiffest 12f around. If you've ever stood in the stands and looked across at the uphill first 6f, you'll understand why. Contrary to myth, non-stayers don't win it, especially if the pace is a true one. Those who argue Sir Ivor won it despite not getting the trip conveniently ignore the fact that he subsequently won the Washington DC International over the same distance.
There are real stamina doubts about Dawn Approach, Magician, Chopin and Mars. There are none about Ruler Of The World, Battle Of Marengo, Ocovango and Libertarian. Provided this year's race is truly-run, I'd expect the winner to come from the second group.
