Good decisions by the refs on both reviewed plays. Both were correctly assessed minor penalties. Both were fouls but neither was a major penalty foul. This check by the Norwegian player was a normal interference, there was nothing dirty about it.
To the game: The Czechs seem to finally gain some confidence after that sequence with two goals (3rd, 4th), while the Norwegians seem to have heavy legs already. It's a back to back game for them, and obviously the score doesn't help either, it is hard to maintain the enthusiasm when you are 3-4 goals down. The sequence between the Norwegian goal and the 3rd Czech goal probably was the game breaker. If Norway scored the equalizer the game would look much different.
The Czechs are definitely looking more "in the game" than vs. Slovakia, they are skating better, finishing their checks, playing with a greater committment overall. But it is still by no means the optimal perfomance. The new defensemen in the lineup (Prčík, Galvas) are looking good so far. Židlický is a bit of "wild bullet", his reading of the game is below average just like his cooperation skills, but he skates well and plays a physical game, which is probably what the coaches want from him. He might make some impact against stronger opponents in the terms of causing havoc on the forecheck and maybe force some turnover.
The thing I really like about Norway is the competitiveness of all players. Sometimes it is apparent that not every player on the team is exactly great in puck control and other individual skills, but none of them is afraid of physical contact, even with bigger opponents, and they go grinding on the forecheck whenever they have the opportunity. They had been considered the clear relegation contender, but haven't been looking like that at all.
