Think they need another pure finisher down the depth chart honestly.
Hard workers are great, but you need someone who can turn the tide of a game with one good shot. During the cup run that was Burky for us(And Kadri) and I dont think we've really been able to replace him since then.
Guys like Lehky, Colton, LOC, Wood, Olofsson, Kiviranta, Cogs... They're all good hard working types but none of them are snipers or good goal scorers.
Its part of why I think Patty Kane would be an interesting add. Hard to say with Kovalenko but I expect if he sticks in the NHL he'll be another one in the mold of Lehky/Nuke and not a pure goal scoring type.
