I remember there was an interesting article with his countryman Boris Valabik, a former Thrashers player, a year ago. A lot was discussed about why the young slovak players don't make it out of camps and their experience when they come to the camp in US/Canada for the first time.
"It's a huge shock for them. The intensity of the training and the attention to the detail that is suddenly required from them. What they thought was hockey in Europe is not the same there. In America, it is taken quite differently, in more details, more intensively."
One of the question was also why Bakos got injured during the Bruins preseason camp. His answer was self explaining:
"
These injuries come due to the intensity of the workouts in the practice. The exercises are as intense as the regular game itself. Even if a players can manage one game, he can feel exhausted after just a week. Then the body can not handle it and gets hurt."
I think this could explain exactly why Cehlarik was never able so far to have a consistency in his game. After his call ups he would have a strong 2-3 games and then slowly fade away or had some kind of injury.
I guess this would also answer the reference by Cassidy of "has no NHL pace"during the camp in China last year. The coach saw it before we could see it.
In case anybody wanted a link to the article(in slovak):
