I've watched quite a few Iowa games this year. Lambos has been moved to the third pairing - while his skating is fantastic and his main asset, he doesn't process the game well. Routine breakouts can become a huge turnover that ends up in the back of the net. In fact, he was scratched recently after making two terrible plays that directly led to goals. He can be a bit spazzy out there, too, when he is pressured.
I have not seen him learn this year - in other words, watching him this last weekend he looked similar to what he did in October. There is the fact that Iowa is terrible and there hasn't been a lot of positive there, but I would say that I've noticed other players improve throughout the year, where as Lambos has looked the same.
I don't see a long future in the NHL for him due to his lack of hockey IQ. Hope I am wrong.
