Johnny V's mounts (almost a thousand of them) have yielded a 27.5% loss per every dollar bet on them over the last 12 months.
Ramon yields a 14% loss. He's still profitable in turf races (barely)
From 2001 to 2009, Ramon had a profit in turf route races 8 out of 9 years, and a giant profit over that combined 9 year stretch of time.
In his case, it's not that he's declining as a jockey, it's more his value as a jockey to a bettor is declining because his reputation has grown so much. His value stats are sh!t now compared to what they were 10 years ago before he had people scores of people looking to bet him almost blindly.
