Musto's track record ain't looking too pretty these days. Strome, Nylander, and Mitchell have all disappointed to various levels (though they are all still young), and while no fault of anyone's, his two main guys this past draft (Rossi and Khustnutdinov) both had some health issues that hurt their D+1 season. So obviously Musto is one big ol' jinx.
Lambos is a reach now, but he was likely top ten (maybe top 5) before this past season started. Hawks love guys who had huge value and had said value drop just enough to be attainable. They could very well believe that Lambos' injury issues aren't of any concern and see him have a strong season in a year where he isn't playing in a new league in a shortened season (like he did this year, going from the WHL to overseas).
Having said that, who knows who we pick. I do know that Hawks like Kaiden Guhle last year, so maybe they feel a need for a physical LHD in the future. Don't know, but wouldn't be upset at Lambos being the guy at #11.
