very intelligent way of looking at things.
thx, that happens oftenly to coaches when they had big success and than a big failure, they get anxious and defensive in their mind, and start to do mistakes.
It's even harder for coaches of NTs, they have to wait 1 year (or 4 for Olympics) after a disappointment to redeem themselves, and can't just work off the bad taste after a short holiday. so the bitterness stays and they will be oftenly confronted with the last results. For most of them, it's a awful lot of mind work to get back the confidence and all that hinders them from going all through that trouble again a year later, is reduced to 2 or 3 "must-win" games. It's really freaky mentally.
We had the same story here in Switzerland with Krueger. He was golden in the beginning (4th at WC in Switzerland 1998), and feed Swiss Hockey with a lot of positive enthusiasm, but after the Olympics 2002, where they were eliminated in a group with Belarus, Ukraine and France, and heavy critics by the press and fans, he lost a lot of confidence... and never got it back fully.
He still got very solid results and a few highlights, e.g. 5th at OG 2006 with century wins against Canada and Czechia, swiss hockey owes him a lot. But there was a problem. He still was preaching the positive mind, but wasn't fully convinced anymore, he lost the believe in the skills of the players and tried to put them in a very destructive system with as good as no attack against stronger competition. they had to play without there full skillset. as long as success is there it might works somehow. but finally more and more skilled players refused to play under this system. the team didn't progress, and IMO the last 4 years were lost years for the all-around development of them.
While I don't know much about the problems concerning Bykov, I just hope russian federation doesn't do the same mistake and keep Bykov too long only for his early great success.
