The medical staff hasn't cleared him to play baseball. Your speculation about his injury is entirely useless. Forming an opinion off of such useless speculation is extraordinarily silly, bordering on intentionally oblivious.
You say there is "not a shred of evidence showing us what the injury is" - I've already called this entitled behavior out for what it is, however it's funny to me that you can't see the obvious hypocrisy in noting this and then immediately speculating as to the nature of his injury. They haven't given information (because you're not entitled to this), and yet you're spinning that as if it means he's perfectly healthy. Copy/pasting a definition you found online of diagnostic imaging isn't really an argument. A clean MRI does not mean he's healthy which, again, is why the medical staff didn't clear him to play baseball.
You have to understand how illogical that is. "I personally don't think he's hurt" could not be further from a fact, and it's honestly pretty funny you think it's smart to portray it as such.
Byron Buxton has a very unfortunate and frequent injury history which has prevented him from playing as much baseball as any of us would like - Byron Buxton most of all. Making that out to be some kind of moral failing is childish behavior, particularly when I have provided you with evidence that he spent 10+ hours in the training room daily for months simply to DH for the Twins last season. Saying he has a low threshold for pain with absolutely nothing to support that should be embarrassing.
I haven't insulted you, I said your opinions are entirely baseless and objectively wrong given what we know for a fact about Byron Buxton's character. My characterization of your words is not an insult. You simply have not paid attention to that aspect of Byron Buxton's career and you are woefully uninformed to call him soft, or to say he's choosing not to play. That he's back in the lineup tomorrow is even more evidence that he isn't choosing to sit out, and yet you choose to spin that so that you can remain biased against him. That much is entirely evident.
