I posted this response on the Chicago board I follow so I better post it on here for my west coast friends...
It's obvious you put a lot of time into this analysis but your take on Moonlight Cloud in the Mile needs some adjustments.
First off she's a filly. Secondly there is nothing free wheeling and being alone on the lead in her performances this year. In the Moulin she was near the pace as it was a tactical race with only four runners. Godolphin's Farhh set the pace trying to test the stamina of the filly but she prevailed.
In her prior race in the Le Marois, she was in mid-pack and met significant trouble in running but managed a fourth behind 3 Group 1 winners including Excelebration. She was also just off the pace in the Maurice de Gheest before taking the lead 2 out and easing down for a win over subsequent G1 Arc day winner Wizz Kid.
Finally in the race that most Americans likely saw, Moonlight Cloud was mid-pack and made a storming run home in the Golden Jubilee to just go down by a diminishing head to super filly Black Caviar at Royal Ascot. The company she has kept in her 4 Group 1 starts this year demonstrates her to be very live next Saturday and it won't be as a free wheeling front runner with Obviously and Little Mike. She will likely be in the middle towards the back of the field and will likely be rattling home late. Her Ascot run was on good ground so the surface at Santa Anita should suit and the question of her stamina is less likely to harm her on the fast, flat surface in Arcadia.
As for Excelebration I would agree with you that the two week turnaround is a major concern. However he was far from all out in the QE II with his biggest question being extricating himself from being blocked in on the rail. When he found an opening he accelerated to the lead without being asked and won easily. As for the pace scenario in the Mile, it should also suit him. He should be laying closer than Moonlight Cloud but still in mid pack. At the top of the straight he should be laying 3rd or 4th with Wise Dan and if the two week turnaround and travel don't do him in you could see quite a battle between two very good milers. If Moonlight Cloud avoids trouble coming from the back, the boys better watch their back.
