While not generational, Jack Eichel was a consensus 1A center. The kid can't stay health but he's a PPG center. Their blueline was pretty solid all around. Martinez-Pietroangelo, McNabb-Theodore, Hauge-Whitecloud. There's two cup winning defensemen on that 1st pairing. There's LTIR shenanigans as well. Someone could probably make a score card that gives each one of these pieces a score, each position probably has a maximum value, and then figure out a minimum score that is historically needed to win.
