Boston won the Stanley Cup in 2011 with Chiarelli as GM.
Draisaitl had a goal and assist, and Matt Benning scored for Edmonton (23-24-3), which has lost three straight.
Todd McLellan, whom Chiarelli hired as coach in 2015, was sacked in November after the Oilers started 9-10-1 this season.
Despite firing the person responsible for putting the roster together, Oilers Entertainment Group CEO & vice chair Bob Nicholson threw the gauntlet to the players Wednesday.
Nicholson clarified that the decision to fire Chiarelli already had been made before the game and that the first two periods going differently Tuesday night - the Red Wings held a 2-0 lead - would not have changed his mind.
Nothing else about Chiarelli's tenure in Edmonton was quiet.
The Oilers got caught scrambling midway through the second, leading to a backhanded goal by Glendening.
"When you're chasing games like we're doing right now, that's a formula for losing", Oilers coach Ken Hitchcock said. "We'll make some trades at the deadline if they're the right trades to get us in the playoffs, but not giving away the future". The Philadelphia Flyers dismissed Ron Hextall in November and named Chuck Fletcher his replacement.
Nicholson says Chiarelli was disappointed by the news, but not surprised. Hall won the Hart Trophy as NHL MVP last season. He has also inked underperforming forward Milan Lucic to a multi-year millstone contract at US$6 million per season.
Zuccarello, 31, is having a nice season for NY, and through 35 games he has 24 points, including eight goals and 16 assists. The first-round pick sent to the Islanders by Edmonton in the trade was used to draft Mathew Barzal, the 2017-18 National Hockey League rookie of the year. The Oilers put Spooner on waivers Monday. It was understood by most that the Oilers' brass would be on a short leash this season, and 49 points in January simply wasn't good enough to keep Chiarelli around. However, the Edmonton Oilers have continued to flounder for the past two seasons, despite outstanding play from the young star. The Oilers have missed the playoffs in all but one season since 2006, failing to put together a decent team despite winning the draft lottery four times.
Chiarelli had the brilliant idea of signing Drake Caggiula out of North Dakota.
Chiarelli made another controversial move roughly 24 hours before his firing, signing goalie Mikko Koskinen to a three-year, $13.5 million contract extension with trade protection.
