In a soccer match, based on the attacking and defending situation on the field, the goalkeeper will move back and forth in front of the goal. If we take the goal line as the reference, moving forward is recorded as a positive number, and moving backward is recorded as a negative number. The movement record of a goalkeeper during a period of time is as follows (unit: $m): +7, -3, +8, +4, -6, -8, +14, -15. (Assume that the timing starts when the goalkeeper is exactly on the goal line)
(1) Does the goalkeeper return to the goal line at the end?
(2) Assuming the goalkeeper consumes 0.1 calories of energy for every 1 meter run, how many calories of energy did the goalkeeper consume during this period?
(3) If the goalkeeper is more than 10m away from the goal line (excluding 10m), the opponent's player is highly likely to score a goal with a lob shot. How many opportunities does the opponent's player have to score a goal with a lob shot during this period? Briefly explain the reason.
