Do any of you remember what Hitch did to Hull and Madano? It literally took some of the greatest players of all time to over come his all in defense and f*** everything else strategy.
He turned Hull into a Cup winner. Hull has repeatedly talked about Hitch turning him into a better all-around player and cited his own defensive shortcomings as a reason that he never won a Cup before 1999.
In 1998 Dallas lost in the Conference Final to the defending (and eventual) Cup champ Red Wings. They added Hull and won the Cup the next season. In 2000, they defended their Cup all the way to game 6 of the Final where they fell to the Devils. Hull/Modano were 1st/2nd in playoff goals and points that year. The 1999 Cup was the first for both of them even though each had been in the league for 10+ years.
No teams won Cups in that era without some of the greatest players of all time. From 1994/95-2002/03 the league saw 4 total Cup winners: The Devils (3x), Red Wings (3x), Avalanche (2x), and Stars. These were also the only teams of the era to make multiple trips to the Final over this 9 year period.
The Devils had the Brodeur/Stevens/Niedermayer era-defining trap trio of Hall of Famers that includes a consensus top 5 goalie of all time (who most have top 3 and some have #1).
The Red Wings had 7 Hall of Famers on the 98 and 99 teams. Yzerman, Fedorov, Lidstrom, and Shanahan were all younger than Hull/Modano were for the Stars Cup run and every bit as good (and most would argue better) than the Dallas core. They had 9 Hall of Famers on the 2002 team.
The Avs had the best playoff goalie of all time and the 1-2 punch of prime-aged Sakic and Forsberg. They added Hall of Fame D men Bourque and Blake for the 2nd Cup.
"Having some of the greatest players of all time" was a prerequisite for winning the Cup in the dead puck era. The top few teams in the league were outspending the rest of the league like crazy and using free agency to add future Hall of Famers to already-great cores. Dallas never had a skater core as good as Detroit's. While they had the era's 4th best goalie, he still was a clear step below the guys in net for New Jersey and Colorado. Acting like they should (or would) have done more if not for the coach is just ignoring reality. Pointing to that late-90s-early-2000s Stars team as a criticism of Hitch is ridiculous.
Hitch (like pretty much all the "everyone is buying into the system" coaches) eventually lost the room in Dallas. Anyone looking to hire him should absolutely recognize that his effective shelf-life is very unlikely to last more than 5 years (and will probably be more like 3-4 years). But he absolutely made his teams better than the sum of their parts.
Looking at the Blues teams under Hitch, our rosters were clearly outmatched by the class of the West (LA and Chicago). Backes wasn't the same caliber 1C as Kopitar or Toews. Petro wasn't the same caliber 1D as Keith or Doughty.
You can argue that the Shatty/Jax/MacDonald/Oshie/Perron/Steen/Berglund supporting cast was as good as the Mitchell/Scuderi/Voynov/Carter/Richards/Brown/Martinez supporting cast for the 2012 Kings. But even if you give us the edge in complimentary talent, LA had the clear and obvious edge in net with Quick over Elliott. When you lose to a team with a better 1 C, 1D, goaltender and a comparable supporting cast, it is pretty tough to say that the scoring dried up because of the coach.
In 2013 we added Bo and had rookies Schwartz/Tarasenko playing like rookies. However, Voynov took another step for the Kings. Maybe we bridged the talent gap a bit, but we were still worst in the big three positions of 1C, 1D, and in net. Again, hard to say that the reason we lost in 6 was due to getting tired.
In 2014, Tarasenko and Schwartz had arrived as genuine contributors. We swapped McDonald out for Sobotka and genuinely had more offensive talent. We played Chicago this year and while we had more offensive talent, we still lagged behind at 1C and 1D. We also didn't have anyone on the roster even approaching Kane's talent level. Hossa was a better all-around player than Steen and Seabrook/Hjalmarsson was a better set of 2-3 D than Bo/Shatty. We were outclassed up and down the lineup.
We underachieved in 2015 and should have beaten the Wild. But then in the following season we knocked out the defending champ Hawks (who were still absolutely in a Cup window) and got to the Conference Final. I just don't see an argument that this era of Blues teams should have accomplished more than they did under Hitch or that his system left them unable to reach their playoff potential.
