Pointing out how they've only won 1 playoff series in that time span, while ignoring they wouldn't have ever even made the playoffs with Richards/Carter on the team instead of Voracek, Simmonds, Couturier, and Schenn in that time span, let alone take the eventual EC champs to 7 games with a crippled Emery tending net in 3 of those games is hilarious.
No we're not trading Giroux because of a bad stretch(while his value is at an all time low as he's playing the worst hockey of his career). Yes he was on pace for a 70 point season 2 months ago. His demise is being greatly exaggerated. The whole team is not scoring because of a defense first strategy the coach has implemented
Perhaps the real reason they haven't made it out of the first round is the hilariously bad blue line they've assembled in that time span? Pronger got hurt. Missed out in Suter and Weber in 2012. Wound up with Striet and then Kimmos blood clots sent him into retirement earlier then we hoped. 3 years ago we started a mini rebuild by building the blue line via draft and so far it's paying divedends. Provorov and Ghost are Studs. Gudas is a top 4 player as well. That leaves 3 spots for 4 highly Touted guys in Sanheim, Myers, Morin, and Haag.
So no we're not trading Giroux and this writer you're citing is a fence post. While he points out plausible things in this article the team is not going to panic and trade the best players it's had in 20 years over a bad 30 game stretch in which the whole team is struggling. Next time you want to point out shortcoming of a franchise you know nothing about, perhaps do a little research.
