"It's going to be the puck management," Canadiens assistant coach Luke Richardson said.
Montreal committed turnovers that led directly to Tampa Bay's first three goals. The first two turnovers came on lateral passes high in the offensive zone that were picked off and quickly transitioned into counterattack rushes. The third turnover that led to a Lightning goal resulted from an errant pass through the neutral zone.
Canadiens goalie Carey Price has covered up for many of their mistakes in the Stanley Cup Playoffs to help them reach this point, but they'll need to play smarter in front of him in Game 2 of the best-of-7 series at Tampa Bay on Wednesday (8 p.m. ET; NBCSN, CBC, SN, TVAS). The five goals Monday were the most Price has allowed in a game this postseason.
"That's a team that thrives on turnovers," said defenseman Ben Chiarot, who scored Montreal's lone goal in the second period. "They're pretty quick coming back the other way every time there's a turnover at their blue line, so (it's) definitely something we have to be aware of and make sure we're a little smarter with the puck."

It was a particularly tough night for the line of Tyler Toffoli, Nick Suzuki and rookie Cole Caufield, who were on the ice for three goals against Tampa Bay's top line of Ondrej Palat, Brayden Point and Nikita Kucherov.
It started with Point intercepting Caufield's pass high in the Lightning zone. That led to a rush the other way that defenseman Erik Cernak capped by redirecting Palat's pass from the left wing over Price's glove to make it 1-0 at 6:19 of the first period.
Canadiens forward Brendan Gallagher committed another turnover in the offensive zone that led to Yanni Gourde's goal that gave the Lightning a 2-0 lead at 5:47 of the second period.
"You can't do that against that team," Richardson said. "They're going to counter quick like they did tonight and make you pay. So, we've got to just clean up our puck management, make sure we're laying pucks in behind them and get back to forecheck that we do well and create some more O-zone time for ourselves."
