Again, I apologize for inaccurately expressing my thoughts.
I think Buxton's past incaution in certain situations, such as running into fences, increased his risk of injury. During the last three seasons he appears to have learned from his past and to have become more aware of putting himself at higher risk, and I don't think that any of his injuries during the last two seasons were the result of incaution. Nor do I believe future injuries he may suffer are likely to be due to this. He has also taken steps to improve his physical conditioning.
I have seen no data to suggest that Buxton is physiologically injury prone. If you believe that to be the case, the burden is on you to produce data to support that hypothesis. Again, keep in mind that it is invalid to use population-based statistics to prove or disprove an hypothesis about an individual. If you are unable to produce this data you should refrain from making such an assertion.
Due to the absence of data to suggest that Buxton is physiologically injury prone and due to his having taken steps to reduce his injury risk, it appears to me that bad luck is the biggest factor in his missing as many games as he has in recent seasons.
