Double post so I can comment on my thoughts as a whole.
I think these selections drastically undervalue the value of a Cup win and drastically overvalue the contributions of guys that consistently got the team to the playoffs but couldn't get over the hump. As I stated above, I would have chosen Schwartz over Steen as the LW for that reason.
I can live with Backes being chosen over ROR. ROR had an amazing year in the final season of the decade, but I get the argument that Backes was the heart and soul for 6 years and was captain when we made a WCF run. This is the one position where I would have prioritized "lengthy contribution throughout the decade" over a "massive contribution to the Cup."
"Jay Bouwmeester was a crucial part of the Blues lineup through the latter half of the decade but always played a second-fiddle role behind Shattenkirk." What a brutal take. Bo averaged over a minute a night more than Shatty throughout their tenure as Blues and that gap went up to almost 2 minutes a night in the playoffs. Shatty wasn't even here for the last 3 seasons of the decade, so I don't know how the hell you can believe Bo played 2nd fiddle to him through the latter half of the decade. Shatty absolutely shouldn't be on this list. He was very good as a Blue, but the article even mentions that he played on the left side for less than 50% of his time here. He was here for the WCF run, but was largely played on the right side during that playoff run. Bo/Petro was the top pair with the 2nd pair most often being Gunnar/Parayko. Shatty took some shifts on the left side in offensive situations, but his regular deployment in that run was as the 3 RD at even strength while quarterbacking the top PP unit. He was 4th in even strength TOI per game among our D men in that run, playing 4:30 a night less than Bo at even strength. He played a significantly smaller LD role than Bo when they were here together, he played a lesser role than Bo during our WCF run when they were here together and he wasn't here for our Cup run where we leaned on LD Bo to play 23:30 a night and be half of the best shut down pair in the NHL. On top of playing a substantially larger role than Shatty during our 2 deep playoff runs (and actually winning the Cup), Bo played more games as a Blue during this decade than Shatty did. There is no way Bo shouldn't be the LD on the all-decade team. He has been the top pairing LD every year he has been here but one. The one year he wasn't was the 17/18 season where he gutted through his hip injury and missed almost 50 games.
Goalie: There is at least some validity to this argument, since Binner only had 1 (partial) season with the NHL club during the decade. But Binner had a monster year to save our season last year, became one of a handful of faces for the franchise and will always be remembered as the best money goalie in the history of the franchise for his performance in the back half of playoff series in 2019. If your putting Backes over ROR to represent the first half of the decade, Binner beats out Elliott.
All in all, it is bizarre to me that every single close(ish) call here deferred to the guy who was here longer but never helped the team get over the hump. Half of the selections weren't here for the franchise's first Cup. Of the 3 who were here, Steen was on the tail end of his career and is on the list for his contributions to non-Cup teams. He was selected as the LW representative, which is not the position he played for his contribution to the Cup. So that's 4 of 6 selections who were picked for their work outside of the Cup win. Petro and Tarasenko both would have been locks at their position even had we not won the Cup last year as they were clearly the top performer of their position for the entire decade. How on Earth are none of these selections given to a guy who came in and put a good team over the hump? This is exactly how the list would have looked after the 2016 WCF run (although I would have still argued for Bo over Shatty at LD since he actually played that position). How does the all-decade team not get a single guy who is on their specifically for his contribution to the franchise's first Cup?
