The 2015 Stanley Cup was all about defense. The games that Chicago won, they won 2-1, 2-1, 2-1, and 2-0.
Teuvo Teravainen scored 4 points in 6 games. Marian Hossa scored 4 points in 6 games. They were Chicago's top scorers, but even they did not score a lot. When Chicago won, they won because of a historically good blue line. Duncan Keith, Brent Seabrook, Niklas Hjalmarsson, and Johnny Oduya. And one of the best two-way centers in the game at the time, Jonathan Toews.
It's funny because if you asked me, I'd say the Chicago defense was better than the Dallas defense. And if you asked me, I'd say Toews was better defensively than anyone on the Dallas team. And if you asked me, I'd say this current Lightning team is better than the one in 2015.
But this is where legends are made. If you step into that rink as contenders and walk out that ring and champions, the theoretical comparisons won't matter. There are two questions. One is uninteresting, and that is "can the lightning be shut down." And the answer is always going to be yes. And the other question, "is Dallas the team to do it."
That remains to be seen.
