re: how does Bregmans power project in the majors?

If you've played at any level of competitive baseball then everyone is a guess hitter to some degree. It's a part of hitting. Simply decided that you won't swing at a certain pitch requires some thought to it before the pitch is even delivered. Now to what extent is a different story. I somewhat agree with your statement though he isn't as bad as some ppl here are making him out to be.
