Tampa Bay: "Why not both?"
I voted for two 1Cs
Pittsburgh: Crosby, Malkin
LA 2012-2014: Kopitar, Carter
Nashville/San Jose were good examples of two 1Ds but came up short. Although you can argue San Jose had Thornton (Hart-worthy 2015-16 year) and Couture were that combo when they had Vlasic and Burns in the cup final.
Gotta put the puck in the net and with the right system a team can thrive with weaker D (Pittsburgh had a brutal D on paper in 2016 after round 2 I believe).
