I mean... you're not wrong... but that's in a vacuum. By the time the defense picked dancing partners the forwards were already squared off. Marino got to pick between Trouba and Miller.
He did pick the lesser fighter of the two (I don't think Miller has had an NHL scrap before this... but maybe I'm wrong).
That said, if both coaches knew what was going to happen, I think you would have seen Cuylle and Lindgren out there for the Rangers rather than Vesey and Miller, and Smith rather than Marino.
It was a no-win situation for Marino. Both Rangers defensemen had a few inches on him and 30 pounds. The other poster referring to either of them as "the weakest link" when they've both got a significant size/weight advantage on Marino is completely dishonest though.
Agreed that neither coach was planning on all the guys fighting, as they would've had at least a few different players out there.
