But Drouin returned to Syracuse in March and was called up by the Lightning during the final week of the regular season after Stamkos' blood clot was discovered. Drouin scored a goal in his first game back with Tampa Bay, on April 4, and rode that positive momentum into the playoffs, when he had five goals and nine assists in 17 games, including the game-winning goal in Game 2 of the second round against the New York Islanders.
Drouin, 21, will get every opportunity to be the setup man for Stamkos -- and that's exactly what the Lightning were hoping he would be when they drafted him. Drouin has 42 points (eight goals, 34 assists) in 91 NHL regular-season games over two seasons.
The "Triplets" line of Nikita Kucherov, Ondrej Palat and Tyler Johnson remains intact. Kucherov, a resticted free agent who remains unsigned, scored 30 goals for the first time in his NHL career and led the Lightning with 66 points last season.
Much of the Lightning's roster has been unchanged through the past three years, but some players will be left exposed in the NHL expansion draft next June.
"Between now and the start of 2017-18, if we're going to sign all the players, we're going to have to make some changes," Yzerman said in July. "To what extent I'm not sure, but we're not going to be able to simply sign every guy and keep the exact same group together. It's not possible."
