It does seem like the Jets did typical patchwork. Capobianco wasn't coming back and the Moose need someone who can QB a PP with Heinola graduating too. I'm not sure if Salomonsson will be that guy, time will tell. Coughlan is at least an option
Lundmark has been given a steady defensive role for the past 2 seasons on the Moose. He has developed some chemistry with Heinola over 3 seasons, and last season they were given the shutdown role, when Heinola finally got healthy. Before that I believe he was tied to Ashton Sauntner and that's a considerable talent drop off. Capobianco and before him Chisholm had been given more offensive roles in the minors. So I think the organization saw strides in his defensive game...
He's a good skater, and has the size to play in the NHL. I think it just comes down to opportunity now. If the Jets need a defensive callup during the season he might be first in line, assuming he clears waivers.
