I've honestly been thinking of this all day. And that's not even a joke (I'm spending some hotel nights in a small town for work, not much to do).
Clearly on the bottom pair you absolutely cannot have Smid and Engels playing together. That was good for a goal against a game this year.
BroDano was one of the best in the league and I think that'll stay together.
Russell - Wideman was good, really good this year... But I don't think that Wideman can repeat the year he had this year. Russell's a great little dman with some good skating ability, positioning and blocking everything including cell signals.
Engelland did great when paired with someone who can skate. Witherspoon is a stay at home guy too... So; I don't know if that'd be the best answer for Calgary.
There's a lot to figure out here. You could trade Wideman while his value is at an all time high and see if you could upgrade the middle pair completely? There's some good top 4 guys available, like I think Sekera would kill in Calgary. I also think we need some more muscle in the top 4. It's nice when you have someone who clears the net; but it can't be the guy who only plays 14 minutes a night. Dunno, a lot of questions for sure.
