Working a count doesn't make you passive, just look at the Nat's lineup!
It makes you smart, you attack pitches you're able to handle instead of chasing bad pitches.
The problem with Crawford is probably swing mechanics, he generated zero power.
They probably didn't want to change it immediately, let him get comfortable, but at some point I'm sure they've made adjustments.
And players often take time to absorb new mechanics to the point where it's second nature.
Of course, the fact that he struggles to make adjustments suggests he's not as talented as the hype suggested, one mark of a top athlete is the ability to adjust his swing and approach quickly to eliminate any recognized weaknesses. Performance is more important than potential.
This is also why you should pretty much ignore the post-college 1st year performance because of the adjustment from aluminum to wood bats, for pitchers, they have to learn to throw inside (hard to jam an aluminum bat), for hitters, to handle inside pitches.
