Narrative:

Departing runway 28R rolling down the runway at about 100kts noticed an aircraft entering the runway from right to left and not stopping. I maneuver the aircraft to the left of the centerline to avoid a collision with the said aircraft. Once cleared returned to the centerline and departed.I think the other aircraft missed its turn and entered the runway.
