In the Blackhawks series Boudreau had home ice but it was Q that dictated the matchups. So Q took Toews away from Kesler - who was losing the possession battle but limiting legit scoring chances rom Toews and co - and put him up against Getzlaf, who Toews proceeded to eat alive. Boudreau tried to get Getzlaf away from Toews, but he couldn't, which only served to unnerve and throw off Getzlaf, if post-game interviews are anything to go by.
Also, the entire tactic of 'beating up' the Blackhawks and wearing them down was idiotic to start with. Prior to the Ducks series the Blackhawks had beaten the Kings, the Bruins, the Blues, and gone 7 games with the Kings. You really think physicality is some magical, terrifying thing the Blackhawks have never stared down before?
A quick glance at their record in games 1-3 vs 4-7 shows they get stronger as a series goes on, not weaker. The teams that have beaten the Blackhawks in the modern era have all reached 3-1 in the first 4 (except maybe Phoenix....have to check). You don't beat the Blackhawks by wearing them down, you beat them by blitzing them out of the gate before they can adapt. The idea that every hit you're taking yourself out of position to make is going to pay dividends down the road suggests a coach that hasn't done even baseline research into the opposition.
