Yes, I think some of his early injuries were a lack of caution or bad technique, but as I noted I think he has made changes. However, the injuries he has had are more extensive than just "reckless or bad luck". They are significantly diversified both in terms of how he is hurt and what parts of his body he injures.
Meaning, you can't dismiss the risk that comes with that history merely by chalking it up to bad luck and recklessness. His rib cage injury, wrist injuries, and hip injury all don't fall in either category. Among others. Which means extensive amounts of time missed can't be dismissed so easily as you have tried. Now...what explains that? I don't know. My point was that some athletes ARE more injury prone. They can get hurt more often regardless of luck or recklessness because their muscles/bones are predisposed to injury. Is Buxton necessarily in that camp? No. I can't prove that. Likewise, you can't dismiss the possibility he is either. Neither of us have the necessary information for a conclusion. We are talking about the future so we are dealing in possibilities and probabilities. I have never dismissed the fact that he might be suddenly healthy. (Go ahead and check. I said that's why I gamble on the extension) You, however, did dismiss the alternative: that this is a case of an athlete who won't see this go away. We know this can and does happen. (The idea that "injury prone" isn't real, again, I demonstrably proved false)
Take his current manager, such a diagnosis may come after years of injuries. To claim, as you did, that past injury history has no bearing on future ones is plainly false in MANY cases. Now, it isn't necessarily an indicator either, but that's where risk comes in. And our conversation was about risks and 7 year contracts into the future. It's plainly, scientifically true that he MAY have such risk and there is evidence it MAY be true of him considering the wide swath of injuries he has endured and his difficulties coming back from them. It is plainly false to dismiss the connection between past injuries and future ones because athletes CAN be predisposed to injury regardless of whether they seem connected at the time. Again, I proved this with scientific citation as well as the fact that it just makes sense from the "common sense" perspective.
I don't think this is controversial. Could these half a thousand games he missed since his draft day be a series of crazy bad luck? Sure. Could it also be that for all Buxton's genetic gifts that got him here, he had some unfortunate genetics for durability and endurance? Sure. Time will tell, but when predicting the future we only have the past and what we know about age/human bodies/etc. to inform us. The Twins should recognize the risk and invest accordingly - give him a comfortable base, pay the man if he plays, but protect yourself in case this problem isn't going away - because it very well might not.
