Hiring Jim Elmer Benning. Without him, we likely end up with some combination of the players we have along with (minus JT Miller and maybe a few others):
Nylander/Ehlers, M. Tkachuk, Forsling, Theodore (Kesler trade), McCann, DeBrincat/Dunn (Gudbranson trade), Andersson (Baertschi trade), Guenther/Sillinger (OEL trade), Stankoven, Tanev, Toffoli, multiple 2nd/3rd round picks in other trades, etc. this doesn’t even factor in free agency moves and other trades (like trading Hamhuis/Ryan Miller/etc. as pending free agents when we were eliminated).
Easily the worst GM in franchise history.
