Can a bait move too aggressively for crappie?
Yes. The lateral line evolved to recognize the gentle displacement of zooplankton clouds and small minnows, and that is the signature crappie rise to. A violently thumping or erratically ripped bait broadcasts a pressure signal that reads as "wrong size, wrong prey" — nearby fish often sink away from it, especially in cold or heavily pressured water. Save the aggressive action for active summer schools; the rest of the year, a slow glide, a slight quiver, or a dead-still hang is the stronger trigger.
