Re: Hamilton for Volquez - then & now
I see no need to over-intellectualize this. Practically speaking, the underlying brain chemistry isn't terribly relevant. If you must take actions to avoid situations and circumstances which have a significant chance of leading you to engage in abuse, it's an issue.
Most people don't have to avoid any and all alcohol in order to avoid abusing it. Hamilton does. Call it whatever you want, but it's something to consider.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
