You just listed a bunch of names that have never played a single NHL game (or <10 ineffective games), plus a guy we gave to Tampa Bay for free out of the goodness of Dean Lombardi's heart.
That's not exactly helpful.
Cernak is a top 4 Damn on the TBL...
Clague got his cup of coffee and did extremely well
JAD has gotten time the last 2 seasons and has looked like our future 3C
The other 3 were drafted the 2 seasons so they'll likely get a look over the next 2 seasons..
As for somebody having to play defense, well we still have Doughty, Walker, Roy, Hutton, Ryan, Forbort, MacD the Goon and Bjornfot, Anderson, Brickley, Clague and LaDue in Ontario that can come up at any time! So try again
