I'll freely acknowledge that a defensive lineup this young brings with it some risk, but IMO they have their veteran d-men already, they're just going to start the year on IR. And even THOSE two guys are on contracts some consider to be problematic.
I mean, I'm looking at this list and there isn't anyone here outside of Gardiner I'd give the time of day to.

Most of these guys are still waiting because injuries and age have set in, or they're just plain ineffective.
Connauton is the filler and I'm fine with him and some combination of Barbs/Graves filling out the bottom pairing until IC/EJ are ready. That's a guy who's been around in the league for a while and is signed to a 1-year deal.
