Husso came over from Europe last year. Learning to play NA game is harder for a goalie than a skater. I wouldn't call that playing for quite some time.
So your argument is that an AHL team does not have an NHL caliber coach like Berube? OK, I can definitely concede that. Most of Veilleux's experience is in Canadian Juniors, which does not have a ton of Russians. Some, but its possible he didn't have many. Ladoceur's experience comes mostly from being an NHL assistant, so he might not have a ton of developmental experience. They are young coaches. I think its far more likely that they aren't the best coaches for Klim, or Klim is just progressing slowly, or the Blues for some reason want him brought along slowly to avoid rushing him, then that the Rampage coaches can't be bothered to coach him right because he is a Blues prospect, not an Avs one. That's what you said, they had no incentive to give him the proper developmental coaching to the NA game. You didn't say they didn't have the tools or abilities, but they didn't have the incentive. Which means they could do so if they wanted but just can't be bothered to do so. That is what I have an issue with, as it is wild speculation with no facts.
