Lindy Ruff won his 600th career game as an NHL head coach when his Dallas Stars came from behind to beat the team that Ruff spent most of his career with, the Buffalo Sabres.
This latest landmark in Ruff's 17-year coaching career has fans questioning where next for Ruff? Perhaps a hall of fame spot?
Now able to boast a coaching record of 600-454-78-94, Ruff has made his latest claim for a hall of fame spot.
The former Stanley Cup finalist began his NHL coaching career with the Florida Panthers as the assistant coach where he stayed for four years helping to lead the Panthers to the Stanley Cup finals only to be beaten by the Colorado Avalanche - this was his first of two appearances in the finals.
He was named head coach of the Buffalo Sabres at the start of the 1997-98 NHL season, a post he would hold for a massive 16 years.
During his time in Buffalo, Ruff guided the Sabres to the 1999 Eastern Conference Championship where he was once again defeated in the Stanley Cup finals, this time by his current team the Dallas Stars.
Ruff lead the Sabres to four Conference Championship games but only managed to win the one.
He took them to just one other Conference semi - final than that of 1999 but reached the quarter - finals three times.
Unfortunately, after just 17 games of the 2012-13 season with the Sabres only winning six games, he was fired from his post.
He took over the Dallas Stars job and has since won 29 of their sixty games under Ruff with Monday's victory his first landmark as Dallas coach.
Ruff is showing no signs of leaving the NHL and is one of the more traditional sights in the league now and Monday's victory over his former side shows that he has a lot left to offer at Dallas.
