It's not all random.
Well, batting average counts HR, which don't factor in to BABIP. That said, the underlying point of BABIP is that while it's not ALL random, the amount of influence a pitcher has to control balls in play is completely dwarfed by the influence on his walks, strikeouts, and homers.
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.
