"I have to give a little more," the forward said during his golf tournament at Le Club Laval-sur-le-Lac in Laval, Quebec, on Thursday.
Drouin matched his NHL career high of 53 points (18 goals, 35 assists) and led the Canadiens with 16 power-play points (three goals, 13 assists) last season, but had 16 points (four goals, 12 assists) over the final 30 games. The Canadiens (44-30-8) finished 14th in the NHL after they were 28th (29-40-13) the season before, but finished two points behind the Columbus Blue Jackets for the second wild card into the Stanley Cup Playoffs from the Eastern Conference.
Drouin, who had three points (one goal, two assists) in his final 18 games, took some of the blame for that.
"Who knows, if it weren't for those 30 games I had at the end of last year, maybe we're in the playoffs," Drouin said. "For me, it's just to be able to look at myself in the mirror and know that I did something to be able to help our team make the playoffs this year."
The No. 3 pick by the Tampa Bay Lightning in the 2013 NHL Draft, Drouin was acquired in a trade with the Lightning for defenseman Mikhail Sergachev on June 15, 2017.
He said he is determined to be a factor for Montreal all season.
"Last year, I fell off towards the end of the season," he said. "This summer, I looked at why that happened and at the things that I can change so that it doesn't happen this year. I have to be consistent for 82 games. We came close to making the playoffs, but we still have a little bit left to go to get there. Everyone is able to give a little bit more, and I need to give even more than that."
