I hear what you're saying but if you want to protect the players, I think you have no choice but to connect the dots and make assumptions in cases like these because it's not like you could ever 100% prove intent. The fact that it was Joseph at the plate, it was behind his head and that Stroman doesn't miss the plate by that much even when he's off is more than enough to make the leap. You can't have pitchers throw at people's head. Someone could get killed. If the cost of policing head hunting is that an innocent pitcher gets punished unfairly from time, that's a more than fair price to pay IMO (not that I think Stroman is innocent in the first place).
