Werenski before last season has been pretty injury free. He has played 78,77,82,63,35, 68 and 13 games season by season in his career. Columbus has several NHL ready defensemen - Blankeberg and Jiricek in Cleveland plus possibly Berni if he doesn't return to Europe.
I really don't think they are concerned about depth.
Well my comment was about feeling a rush to trade a D... I don't think they're afraid of losing depth, but at the same time, I don't think it's a huge issue that needs to be addressed asap.
As for Werenski, I don't wish ill on any player in order to be "right", but the timing of this discussion can't be better... as Werenski was put on IR on the same day you argued he wasn't prone to injuries...
In terms of history, the last 4 seasons:
63/70 (not sure if he would have missed more time though)
35/56 is 62% of games
68/82 is 82% of games
13/82 is not a lot
Last 3 seasons he played max 82% of games, which is 14 games injured. Then you have Boqvist played barely 50% of games too in the last 2 years (was he scratched often though, or is it just due to injuries?).
My point stands. Not sure if there's a rush to trade their extra Ds. Or, they'll have time to showcase them.
