To be sure. When the late-50s Canadiens and early-mid 60s Maple Leafs were dominating, they were sharing talent with five other teams. At the dawn of the Canadiens "final Kingdom" era of the mid-late 70s, there were 20 teams in the league, total. There was a similar number (21) at the beginning of the Islanders' run. Blackhawks are sharing talent with 29 other teams- AND dealing with a salary-cap that's impelled them to shuck valuable pieces of their team in the past, and will impel them to do so again.
For the appropriate tribute to the Blackhawks, consider NOT if they're 'a dynasty,' (it's unproductive to dispute with those who say they're not), NOR try to argue that their players are a reputational match for other great multi-Cup winners in history (they probably aren't). Instead, consider their place among hockey's "greater-than-the-sum-of-their-parts" teams. For starters, just looking at this year, you can't convince me that the Blackhawks are clearly more talented than Anaheim- OR Tampa Bay. [Earlier this decade, you could make a great case that Vancouver yielded nothing to Chicago in terms of talent.] And yet, Chicago has carried on, winning in categories other than skill-level... again and again.
They might be better than the sum of their parts, but you can't downplay their talent, they are clearly one of if not the most talented teams in the nhl the last half decade. Bolts is gonna be debatable because of age, lot of young forwards, but on to the Hawks:
Going into this year:
Toews=Top 5-10 center with Selke defensive abilities.
Keith=Most say a top 3 to the best d-man in the NHL(he just won another Norris).
Kane=Top 5-10 winger in the game and arguably better, coming off a PPG injury shortened season.
Sharp=Top 10-15 winger, coming off a 78pts season and excellent 2-way play.
Hossa=Top 10-15 winger, coming off a 30goal shortened season and excellent 2-way play(5th in Selke voting)
Seabrook=Top 15-25 D-man, coming off a 40pts season in which he got a couple late finish norris votes.
Hjlamarsson=Top 40-60 D-man, coming off a a great year in shutdown minutes.
Saad=Top 30-45 winger, coming off a 47pts season with great 2-way play.
So no, they are supertalented, you'd be selling them short to portray them as even marginal underdogs in talent or on paper. They are one of the most top heavy teams in the NHL by far. Nobody arguably has a better top 4/5 forward core or top pair going into last season(next year, Bolts will have them beat finally with Sharp likely gone), and they rely heavily on them for the most part in the playoffs. Could they be better than the sum of their parts? Arguably, but I'd say marginally if so. It's not like they have had too many dominant playoff runs or division titles or president's cups. The 2010 Cup run was magical, but they were also a deeper team than now, so it's hard to say if that was "better than the sum of their parts".
