In years past brain injuries were very poorly documented. It's really only been in the last 10 years or so that these injuries have started to receive more concern and it's way overdue. In spite of this there are still accusations of players being "Nancy boys", or lazy, or faking. Look at Justin Morneau, for example. It took four years after his concussion in 2010 for him to finally be able to produce up to his abilities, and in all likelihood his most recent one has ended his career. In Mauer's case there is a strong correlation to his concussion and a significant dropoff in his production. We (and especially he) can be encouraged by his recent improvement and hope his recovery continues. To place him at higher risk of subsequent concussions, which increase the risk of permanent impairment, would be a very bad decision. Mauer knows it, his doctors know it, the team knows it and most of us here know it. That's why there is a high level of frustration with suggestions that he be moved back to catcher.
