It's pretty easy to make a strike look like a ball. It's much harder to keep strikes looking like strikes.
A catcher we had last year (12U) had a very mediocre arm, but her transfer and release time was excellent. Her pop time regularly beat another girl with a good arm, but slow feet. She was deceptive. On her throw-downs at the start of each inning, the opposing coaches saw an arching throw to 2B, from a kid who didn't look all that athletic. She threw out a lot of runners.
