Idk that he’s as far away from cracking the NHL here as you think, if we don’t sign another goalie (I don’t expect us to), then there’s a good chance the team sees him as the next one up to the NHL as it stands, which would mean any serious injury would get him into games next season
Sure, he's the #3 at the moment. Do you see him getting more than a chance to be the backup? He literally has to beat everyone in order to rise in the rankings. That is Clara, Clang and Dostal. Sure, he already has edged Clang for now. Elsewhere, he would be groomed for another year in the NHL and given the keys to either the starter or the backup role depending on the performance.
From a simply economical stand point, it would be hard to resist making another roughly 500k for a year more in the NHL than getting competed to hell and back in the AHL for the Ducks - not knowing if you ever get that opportunity again. Suchanek is also not represented by just any agent, he's represented by Allan Walsh,
Another likely possibility is that the Ducks goaltending coach really helped him along, so he wanted to remain with him, not at all uncommon for goaltenders especially. Then there's also the Czechia factor with Dostal.
Or maybe the few dozen too-online people you’re talking about don’t actually represent being highly thought of by actual NHL teams.
I don't brush people's opinions aside. I would wager those people are more knowledgeable than the average reporter when it comes to such details. Those who will write about Suchanek the first time he makes an NHL appearance, accompanied by the mandatory typos in his last name.
If you would like to contribute to the discussion, by all means. You asked where i've seen that, to which I gave you the places that jumped to mind. That is not the sole reason why I think that is, which should be obvious to even the more casual follower, when someone follows the U20 performance with a season he did that teams take notice. Like, look at us now, we're putting him head to head with a recent 1st rounder. Are we what you describe?
