Yikes!
I did not mean to impart my own personal biases onto your runner. He could be anything! I merely stated facts.
I use the pedigree site much too much. It is a habit I am trying to lessen.
My personal bias is against sire sons of Unbridled's Song, who famously had bad feet. He has been a wonderful sire ( a great damsire) but not a great sire of sires. Liam's Map has risen to the top of his sons.
While I regard Arrogate with the same doubt as the others, nothing has been determined. He is off to a slow start, that is all.
