Kubacki going back to his old habit of an extremely high take off and dropping like a sack of potatoes clearly indicates it's a technique issue. The thing snowballed from there. After the Oberstdorf failure Dolezal blamed Stoch's result on the new boots he was using, they got back to the old ones in GaPa and Innsbruck and it only got worse. It's clear Dolezal has no idea what he did wrong in the pre-season and with four weeks until WOG shit will hit the fan very soon.
Zyla is basically a lost cause, he usually does his own thing, only when Horngacher threatened to kick him out of the team if he didn't ditch the awkward in-run position he finally came around. Dolezal doesn't have such authority whatsoever.
