Yeah. I just worry about something more serious, or a collection of less serious injuries that affects his willingness to push. See JL's injuries in 2013 (and his subsequent skittishness in mixed conditions). He's a remarkably resilient kid, but everyone has a tipping point.
For example, I reckon one big element of a prime Rossi's strength used to be that he had never been seriously injured. When he broke his leg in 2010, I think a small part (maybe 0.1%) became a little more cautious. During pre-season testing, he'd dominated the field (and won the first race in Qatar after which he hurt his shoulder in the MX crash). After he returned, Jorge seemed to have the edge.
