Interesting question about chess coaching

I have an interesting topic which came up again today.

I have been asked many times why SPICE students won more titles and have more success than all other collegiate chess programs combined in the past 4-6 years (they won 2 World Championships, Olympiad Gold, 4 World Open Championships, 40 National Titles, including unprecedented 6 consecutive Final Four Championships)?

If all the coaches are competent or good (some even higher rated than me), and understand chess very well, then why some have more success and some less? What do you think? 🙂 The answer is simpler than you think. It is not magic and any coach can do it.
