The addition of Subban was, essentially, the finishing move to a project that's been years in the making.
Some players have matured in the Nashville system, others have been assimilated into it through shrewd trades and free-agent signings by Poile.
For the first time in memory, the Predators are among the most feared offensive teams in the League.
Forward Viktor Arvidsson, 24, had a breakout season with 31 goals after scoring eight in 2015-16. He complements Filip Forsberg, 22, who topped 30 goals for the second straight season. Center Ryan Johansen, 24, tied Arvidsson with a team-high 61 points during the regular season and had been a beast in the playoffs with 13 points until sustaining a season-ending thigh injury in Game 4 of the Western Conference Final.
They are bolstered by productive veterans such as Mike Fisher, who scored 42 points (18 goals, 24 assists) in the regular season, and James Neal, a former Pittsburgh Penguins player who has five goals and one assist in the second and third rounds of the playoffs.
But the Predators, the second wild card from the Western Conference who tied the Calgary Flames for the fewest points (94) among playoff teams, became a legitimate threat to hoist the Stanley Cup when goalie Pekka Rinne caught fire.
His play against the Blackhawks, when he had two shutouts and allowed three goals in four games, set the stage for the domination that has followed. Rinne, 34, is playing some of the best hockey of his NHL career at exactly the right time.
Coach Peter Laviolette puts all this talent in the proper position to win. Few have done it better for longer than Laviolette, who coached his 1,000th NHL game in March. Laviolette won the Stanley Cup as a coach in 2006 with the Carolina Hurricanes and has coached three teams - the Predators, Hurricanes and Philadelphia Flyers -- to the third round of the playoffs.
For those reasons, the Stanley Cup will settle in Nashville in mid-June, kicking off a celebration that will humble this party-mad city.
