You need a secure hike for two moving players to successfully execute a hand off.

Shotgun has a stationary RB, QB gives him the ball when he is ready.

Both (either or) can and do work but a moving RB and a QB grasping for control simultaneously is, a recipe for disaster.
The shotgun eliminates the option for a QB sneak, which would seem to be the best play when inside the 1 yard line. Especially since the ball carrier can be pushed from behind.
