Incorrect, he did not train as per usual, if he had he would have played some preseason games, he did not, but don't take my word for it. To quote Jagr himself "Give me a little bit of time because it was a little bit of a different summer, when you don't have motivation to practice, to go any direction, I didn't know where I gonna play If I ever gonna play, so now I know so I probably gonna need a little more time than usually, but after a while I can promise you i'll do everything to help this team."
He says it 1:08 seconds in
Of course it was a different summer, but that doesn't mean he didn't train. I think you misunderstood what he meant.
Translated from a Czech article from late September:
[Jagr speaking about the Olympics]
"I'd like to talk about the topics: Jagr and international plays and Jagr and Olympics. About two days ago, we did an interview with (Czech reporter) where they asked me what are my aims and options in the upcoming season, and I answered: "firstly, I'd like to return to the NHL for at least one more year, and if that didn't work out, I'd like to play somewhere in Europe, or in Kladno and attempt to get to the Olympics. I spoke honestly, didn't really think about it, I said it how I felt it, and I didn‘t believe it would lead to such humbug, that it would appear in the media next day, that the reporters would start calling all the hockey experts and trainers, asking if (I would be) an asset or not an asset, if it would be good if Jagr played or not...
To explain why I wanted it - how it occurred to me, why I said that -
I believe every human, not just me, but every human, not just in sports but in every job, in life, needs goals. Goals, motivation, and the bigger and harder goals and motivation he chooses, the better job he does. That's why I also need some motivation, some goal, whenever I go into a season. Usually I wanted to be the best hockey player I could be, score as much goals as I could, play well, be as useful to the team as I could be. Now, it occurred to me that the best motivation for me if I don't go the NHL would be to try to return to (the Czech national team). But I didn't think if I was good that I'd be there - it would depend on the trainers, my form, it would depend on various circumstances, whether I'd be useful or not. I can't influence that; the only thing I can influence is pick the best goal I can and go determinedly after it, do the maximum for reaching it.
It doesn't really matter not if I'll be (at the Olympics) or not; what I really wanted was to set a goal for myself so I have motivation for next season, so I didn't just go to the skating ring to just skate around and then go home; I wouldn't be a professional then, I'd be an amateur who does hockey just for fun and I don't want to be that just yet. So I hope you understand I meant it like that, that I didn't want to (cause all this attention), and I'd be the happiest if nobody talked about it anymore, and what shall come will come and that's what I'd say about that. I'd thank all the reporters if they would stop calling the teams and trainers whether or not I should be an asset in the Olympics; I just saw it as my biggest, best motivation if I stay in Europe. Thank you."
Attitude or not training enough was never the problem.
