With what we know about concussions, there needs to be no grey area. Either Joe is clear to play or he is not. Simple as that. Put him through concussion protocols, give him a full evaluation. Get his vision checked from soup to nuts. He should not step into a batting cage until this happens. If he refuses then he doesn't play. I personally think it is outrageous to assume that he still has had post-concussion issues for TWO YEARS and it has just stayed under the radar while he's continued to play. This implies that the Twins and Joe's entire support system can't connect dots or that Joe has never said anything about after TWO YEARS. That is just absurd. I gotta put a lot of the blame on Joe for not having the common sense to speak up. I'm sorry, but what in the world is he thinking??
