How did Hudon get brought into this? They don't compare at all imo, Hudon crushed it in his first pro season, he started out among the top scorers in the league and had the rookie scoring lead until later in the season as he faded over time. He was a 5th round pick that played over 100 NHL games and had over 40 points, when you look at the success rate of 5th round picks, how can anyone complain about Hudon.
Mesar as a 1st round will get much more hype but he has similar problems to that of Ylonen when he turned pro, soft, weak physically, inconsistent efforts. He's clearly shown improvement from his D+1 as you just need to go back to my vids of his games and you will see him half ass plays, not try, look disinterested at times, then watch my Laval vids this year and you will see him blocking shots, throwing hits (he's terrible at it) so while he's still not consistently doing those things, the fact that he is doing those things at least some of the time is a step in the right direction.
No one can say what will happen, which is why I always say that too many around here are too quick to start throwing out the bust word. Take Hudon, if you want to compare him to a current Laval player, Riley Kidney comes to mind. Clearly Kidney has had a much worse go of it then Hudon did as all prospects that lack height, mass, strength, skating and speed have a massive hill to climb. If you just bet against all of them you would look smart most of the time but again it's impossible to know how these kids will develop over time. They could hire a skating coach that just happens to figure out how to help them or they hit the gym way harder then anyone thought possible, etc...
