The average oil deposit is 6000 feet underground. So you can imagine an oil company who drill their wells only 100 feet deep are not in business very long.
Throughout New England, the depth of water is often 300 feet. The farmer drilling 50 foot wells will soon be thirsty.
Coaching improvement is no different.

Are you drilling deep enough?
The coach who drills down deeply in one area (i.e., practicing, experimenting, honing skills, reseraching) will have a much greater chance of success than the coach who is trying one, two, three news things every day.
One deep well is better than 10, 15, or 100 shallow wells.
