Ok I'll play. Now i'm quite new to Lydiard so i'm sure others will have better info than me, but since you addressed me ...
1. First, i'm not sure who was better at his game, Cerutty or Lydiard. So there are two in my world (three if you count my former coach/now mentor but i just choose to look at him that way - he is damn good though).
Second, I assume Lydiard isn't perfect. Perfection is an ideal and is never attained - ever. It's good to aim for but not good to get hung up on. So lets throw that one out.
So who else is really good? Well i said Cerutty. I think he may have some things to offer than Lydiard didn't. Vitaly Petrov is the best technical coach in the world IMO so if you want precision with technique look at Bubka or find some words in English by Petrov himself. In the world of pole vault i count two others as Closer to Petrov than any other i've met. In the world of MD i would be interested in what Brother Colm has done and i still have interest in the whole interval side from Gerschler and Zatopek to the Czech version onto Igloi and the versions used by Cruz and Juontorena and of course Franz Stampl who lived in my city i'm yet to investigate properly. I've probably slowed on msome of this research because once i foudn Arthur i knew i had found the right guy. Then Cerutty came into the mix and i thought here we go. Amybe Stampfl was the third greatest. 2 guys in one city and another 4 hours across the seas. (sorry couldn't help myself)
2. I would be very interested to know but i'm sorry i don't know enough yet. Maybe someone else can list them?
That last bit is pretty dodgy. Are you sure you are being honest as well? So how did i do?
ps HRE i didn't pick you for a fanatic. Fan - fanatic? Maybe just the former?
