Panarin, Zibenijad, Buch etc all broke out when they were around 25. That's a LOT of development time for kids aged 19/20. I keep thinking of the old Romans, they reckoned it took 4 years to build up a recruit (from the age of 20 to 24) to the standard of an elite legionnaire. Look at Zib this year, without that first step explosiveness and speed he is average, with his full speed he is dominant.
Laf looks a bit shell shocked and overwhelmed atm, like Kakko did last year. That knee height back hand pass is not something I'd expect to see from a player like Laf if he was at the top of his game, or Kakko deciding to pass instead of shooting at an open goal from a few feet out.
Once the kids hit their full stride they will be fine, it just sucks to be in that pre-/in between period IF you expect them to dominate from the get go. Even so, it was good to see the kid line tilt the ice against Cup winner standard NHLers (Backstrom line) like they did the last game against the Caps for two periods.
