Quoting: Isles777
Teams that go deep in the playoffs have multiple top 6 players on contracts below their market value. (that can include ELC) - look at this years stanley cup finalists . Taresenko, o’Reilly, pietrangelo, Brayden schenn, Robert Thomas, Bergeron, Marchand, pastrnak, debrusk. The leafs have a great core of players but they are either slightly overpaid or being paid their market value. Hard to win cups like that.
Last years palyoffs really can't be used as an example. It was a really weird year, partly because there is a changing of the guard underway and also it was just a weird playoffs where perfect matchup scenarios happened that altered the whole playoffs.
For example, Tampa's top pair defence were either not playing or playing hurt, stamkos was injured as well and momentum just never swung there way. Columbus wasn't a world beater cinderella story, they got lucky taking on a hurting team. Injuries are always the great equalizer. Carolina going as far as they did had everything to do with matchups. Washington was the higher seed but they were terrible 5v5 last season (worst among playoff teams) and that gave a huge advantage to Carolina. Pittsburgh was broken down and tired last season and ran out of gas against the Islanders who plucky style worked against the older Pens. Carolina against the Islanders in the 2nd round was another good matchup but when they took on Boston, they were outclassed by a team that was better at what Carolina did so well.
San Jose, shouldn't have gotten out of the 1st round but the refs game them that when they called a major with minutes left in a game and the Sharks scored 4 goals on the PP to take the series. It was a travesty, and then it happened again in the 2nd round against Colorado! The off side the refs called after Colorado tied the game was a joke and a half. Once you got to the final, anything can happen and it was a great series but with so many good teams losing due to unlucky crap last playoffs made it the dumbest ever playoffs. So many people I know went 0 for 8 in the first round last season playoff predictions. It was wild but its more of an outlier than anything. I'd be highly surprised if this seasons playoffs are anywhere close to as unpredictable.
I think you'll see sometimes get much better as they grow (Colorado, Toronto, maybe Carolina) and other teams fall back to earth. Pittsburgh likely has 1 or 2 more decent years left, Washington is going to start showing its age now as well. Boston could be a team that starts regressing, eventually Bergeron's bionic body will start to break down.
Younger teams get better and TO is one of the youngest and those young guys still haven't reached their prime.
