I've said here for years, power comes from pulling the ball. You can run into one the opposite way but that's not really how any slugger wants to be living. Our "sluggers" like Vaughn and Eloy are allergic to pulling the ball into the LF bullpen.
Vaughn's problem isn't that he doesn't have Aaron Judge's power, it's that he can't pull the ball in the air with any consistency. IMO of course.
