Realistically seems are a few good options late 1st early to 2nd round:
Sprong, Debrusk, Larsson, Kylington, Juulsen, Boeser, J. Roy, Beauvillier, Jack Roslovic, Chabot, Ek, Gurianov, Samsonov, Harkins, Bittner.
Dosent seem like Svechnikov can fall all the way to 26, some team with a 2nd first round pick (Oilers, Leafs, Jets, Buffalo) would pick him off at latest. But he seems like a Scherbak-type skilled winger.
Boeser, Beauvillier, Roy seem very popular guesses (of course French kids always seem popular target for Montreal to choose), my wildass guess is Kylington.
Sprong seems skilled kid, also seems terribly soft floater in little bit I saw of him; but top six or bust kid.
Same as Gurianov, big skilled Russian, but signed in KHL already and may be a Grigorenko II, but also could be Nichushkin-type power forward. Seems a risky option.
Kylington also another super skating swede d-man, but falling in rankings and has ?? about what he will likely become.
