I asked deepseek AI for the number of crashes for the top 10 Grand Tour Riders for the past 5 years. The data may not be 100% accurate, as we know these generative AI models can be dicey, but I think it is a good starting point. According to deepseek, Roglic has more crashes than the other 9 riders combined.
If you want more detailed information about all the crashes and sources of data, I can provide that. I just didn't want to create too much clutter in this post.
Also, it does say that crashes during sprints often times go unrecorded unless there is an abandonment.
