I never believed Mauer was experiencing lingering concussion effects, and I still don't. I think if anyone in the clubhouse saw any evidence of this, they'd immediately try to help/DL him. I think he just got into a slump and had some bad luck, and now he's recovering from it.
I don't believe concussions are necessarily that cut-and-dried.I'm sure you're right that he was no danger to himself, otherwise he would never be out there on the field.But a nanosecond lag in reaction time may be the difference between "average major leaguer" and "Joe Mauer" (or Ted Williams, or other players with legendary plate discipline), and I don't think it's silly to speculate that the synapses weren't yet firing at their previous high level.
I've never questioned Mauer's toughness or drive to excel, so I'm looking for a better explanation of what I believe I saw in his eyes that first game back, than either randomness on my part or newly re-found determination on Joe's part.
But I don't rule out the randomness explanation either.
We'll never know, until Joe writes his book, and probably not even then.
I'm not sure of the timing, with the weather delay and all, but it appears that Joe hit his HR today after my post.So far, so good, as far as me jinxing him goes.Knocking on wood again.
