Did you think the Blues' offseason moves were good ones? If you did, then you can't blame Armstrong. While you often hear people say you can't judge a trade until some period of time has passed, it's actually the opposite. You have to judge a trade at the time it's made. You can't go back and say, wow, Patrik Berglund played great in Buffalo, the Blues never should have traded him. At the time the trade was made, the O'Reilly deal was a great deal. (Though there are Berglund fans who will disagree.) Was signing Bozak a good move? Perron? Maroon? How you felt about those signings at the time tells you whether or not Armstrong made the right move. Was giving Parayko the contract they gave him a good thing or a bad thing? That was a question you had to answer on July 20, 2017, when they gave him the deal.
So many of the moves Armstrong has made have been, judging from how people have responded, good deals. And his coaching hires have sort of worked. Hitchcock got them to them the conference finals. Yeo didn't work. I usually am inclined to say the players take the rap for losses. They're the ones playing. If the losses go on, as they have this year, then the players are the wrong ones. In that case, it falls on the coach or the GM, depending on what you think the issue is. As I said earlier, Armstrong has to get the next coaching hire right or he won't get another.
