One thing that struck me about Vegas' run this year is that it overturned a few common beliefs regarding Cassidy's coaching, such as:
1. Cassidy relies too much on his star players to get results, as in going to the 'perfection line' too often and not working hard enough to find secondary scoring. Not a bit of it in Vegas. The number one hallmark of the Knights' postseason was their depth, the way they shared the goals and talent around the whole team, and the fact that all 4 lines were important and did their jobs.
2. Cassidy neuters his players and doesn't allow them to play tough, physical hockey and play the body when the opportunity presents. Again, clearly not the case with the VGK. Big tough team that never takes a backwards step, punishes opponents wherever possible and hits to hurt. Florida had outmuscled all the teams in the east but against Vegas they ran into a brick wall. Gudas and Tkachuk in particular had been bullying other teams at will, but the Knights put both on the shelf for periods of time and made all their opponents accountable.
3. Cassidy's defensive system hampers offense and limits offensive production from the back end. Nope. Vegas had little trouble scoring all postseason, despite having comparatively limited outright offensive talent at their disposal. Not a huge amount of points amongst the defenders, it's fair to say, but they did their bit and contributed plenty in transition all the same.
4. Cassidy has a habit of getting outcoached in playoff series. Not this year. The Jets were fairly ordinary and then further weakened by injury so were relative easy beats, but the Oilers, Stars and Panthers were all very good teams coached by capable if not outstanding people who all presented different types of challenges. Bruce and his players dispatched them all with fairly little fuss and it never felt like Cassidy was losing the tactical battle. The Oilers probably did best at getting things on their terms for periods of time, largely through the sheer talent of McDavid and Draisaitl, but they couldn't sustain it for long.
I think all of these past criticisms of Cassidy had some merit - I'm not trying to pretend that he's never had any flaws. All coaches do. Rather what I think we've seen is a combination of some of these beliefs being shown to be overblown or context-specific, plus clear evidence that Cassidy has learned and improved as a coach over the years and has worked to overcome some previous errors and deficiencies. It's not one or the other - it's both. Equally I don't think it can be argued that Bruce 'proving himself' this year allows more blame to be shifted to the Bruins' players for past defeats. It's not as simple as that. It does perhaps give some cause for reflection though on some of the perceptions held regarding those years, for those so inclined.
But that's by and by. For now, good on Butch. Good on Vegas. Good on Stone and Eichel and Marchessault and Hill. The whole team played an excellent, textbook postseason and thoroughly earned their Cup. Whatever the circumstances and advantages behind their origins as an expansion team, no-one is handed a trophy and the current group have worked damn hard to achieve the ultimate success. Perhaps they were a tad lucky to meet 8th seed Florida in the finals, but the Panthers had dispatched the best in the east and I honestly don't see any of those other teams beating the Knights anyway given the form they were in. They were best and fittest when it mattered most, and that's all that need be said.
For the rest of us, there's always next year...
