The first rebuild failed. Army took the reigns in 2010-11. You can see what the roster was then @ >
2010–11 St. Louis Blues season - Wikipedia
The only players that remain are Pietrangelo, Berglund, Steen, & Sobotka for a 2nd tour of duty. This upcoming hockey season will be Army's 9th year as GM. He has quite a bit to do if winning the cup is the ultimate goal.
It's beaten to death but the Blues have one line that can score and a whole bunch of blah. It's extremely doubtful Army is going to trade all of the blah. He's not going to count on Thomas, Kostin, Fabbri, Thompson, and Kyrou to make a legit 2nd line. It's always a possibility Thomas and Kyrou make the roster and have an impact. I would never expect either to take the NHL by storm and score 60+ points. Especially since they'll most likely be relegated to 3rd line minutes.
GM's can let the pressure of winning quickly turn into horrible decisions. I hope Army doesn't do something stupid but it's a pretty safe bet he's feeling the pressure now. It'll be interesting to see what changes he makes this off-season. I'm banking on the Blues not picking in the 1st round. To me that WPG pick is part of a trade until I see a Blues rep walking to the podium.
