Sean Kelly needs to go easy on the "poor bike handler" label he assigns certain riders (Roglic, Thomas etc.).
When a peloton is charging into a sprint or going full gas on narrow roads, it's a lottery. Some riders are also smaller, lighter & get mauled way easier.
I find the whole "this rider is from cross so he's a great bike handler" or "this rider is a better bike handler because he went through all the youth categories" argument completely misplaced with regards to at least 90% of the crashes we witness in modern cycling.
It's a meat grinder out there.
