That was my notion as well
Vilardi requires waivers next year, and hasn't shown much in the NHL
Vilardi had 10 goals and 23 points in 54 games last year, at 21 years old, with questionable linemates. He showed an awful lot in the NHL. He was a rookie coming off two years of not playing hockey and he was pretty good, all things considered. He was better than Byfield, Turcotte, and Kupari, who were put in similar positions this season and did (or are doing) worse. This notion that Vilardi didn't show anything at the NHL level is just nonsense. He's now scoring at over a point per game in the AHL. He should be in the NHL, no question about it.
I'm not saying that Vilardi and Turcotte won't bust — there's a very real chance neither of them amount to much at the NHL level, as with any prospect — but I just don't think that trading both of them and a first for a player we might not actually really need makes a whole lot of sense. LA has Clarke, Faber, Spence, Grans, and Kirsanov in the near future on defense, plus Durzi, Anderson, and Bjornfot in the NHL, to say nothing of guys like Doughty, Roy, and Walker, who are proven NHL players.
I'm not Rob Blake, but if I was, I don't think Chychrun is my target right now.
