Would some time in WBS benefit him to adjust to the smaller ice?
Definitely! But the problem is, being stuck in the AHL isn't going to be as attractive (or financially lucrative) to some degree as a deal to play with his brothers in the Extraliga or KHL. I think if you can make it clear that if he can adjust he'll get a call up, he'd stick around. Or, if he just happens to fall in love with playing in NA (a lot of Czechs have really weird ideas about what life in NA is like and are invariably disappointed when they get there
), and figures it's worth the investment to stick it out and see if he can get an NHL contract.
But I don't think the team is going to be patient like that.
It's the same thing that befalls a lot of international transfers. (And to make it worse, the Extraliga season has already started here, so we're essentially asking a guy to get pulled out midseason for camp and then adjust to the NHL/AHL on the fly without giving him time to acclimate, get situated, etc.)
Frankly, I have my doubts that he'll even make it over because of the NHL's dumb insistence on carrying on an asterisk season.
