Robert led the Sabres with 40 goals during his first full season in blue and gold. Two years later, he became the first in franchise history to post 100 points in a season.
Robert would spend parts of eight seasons in Buffalo, amassing 222 goals and 320 assists in 524 regular season games. The 552 points were eighth best in the NHL during that time. But it was his contributions in the postseason that were perhaps most noteworthy.
Robert scored the first overtime goal in team history in Game 5 of Buffalo's first-round series against the powerhouse Montreal Canadiens on April 10, 1973. The series ended with a Canadiens victory in Game 6, but it was the reaction of the Memorial Auditorium crowd following the loss - a deafening chant of "Thank you, Sabres!" - that would remain as Robert's fondest on-ice memory.
Robert added two more overtime goals during the Sabres' playoff run to the Stanley Cup Final in 1975. He clinched a win for Buffalo in Game 5 of their first-round series with the Canadiens, a crucial victory that gave the Sabres a 3-2 edge in the series.
"When you look back over the history of this team, if you had to go into a game in overtime and say it's predicated on, 'Whoever scores the first goal, that's it, game's over, you win the Stanley Cup. Buffalo, who do you want on the ice?' Well, I can think of many players," former Sabres defenseman and longtime broadcaster Mike Robitaille said.
"I would really have to give a lot of thought to putting Rene Robert on the ice. The bigger the game, the bigger the goal. He had a penchant for that. It wasn't luck. He was good."
It was Robert who ended one of the most unique games in NHL history on May 20, 1975 - Game 5 of the Stanley Cup Final, forever known as "The Fog Game." An 82-degree day in Buffalo created a thick layer of fog along the ice surface inside the The Aud, decreasing visibility and forcing frequent stoppages throughout the contest. The two teams traded goals through regulation, forcing overtime in a must-win game for a Sabres team already trailing 2-0 in the series.
With 1:31 remaining in the overtime period, Robert sped down the right side of the ice and took a shot that emerged from the fog and beat Flyers goalie Bernie Parent down low, forcing the goaltender to stumble down to the ice.
