Apr. 24, 2015: Oilers hire Peter Chiarelli as general manager and president of hockey operations, nine days after his dismissal as Boston Bruins GM and six days after Edmonton wins the draft lottery.

May 19, 2015: The Oilers hire Todd McLellan as head coach. McLellan replaces interim bench boss Todd Nelson, who took over for the fired Dallas Eakins. 

June 26, 2015: Chiarelli selects top prospect and generational talent Connor McDavid first overall in the NHL draft. 

June 26, 2015: At the same draft, Chiarelli trades picks No. 16 and 33 to the New York Islanders for defenseman Griffin Reinhart.

The Islanders use the higher of their two new selections to take future Calder Trophy winner Mathew Barzal. Reinhart ultimately plays 29 games with the Oilers.

June 27, 2015: On Day 2 of the draft, Chiarelli acquires goaltender Cam Talbot and a seventh-round pick from the New York Rangers for a second-round selection, a third-round pick, and a seventh-round choice.

Feb. 27, 2016: Chiarelli deals struggling defenseman Justin Schultz to the Pittsburgh Penguins for a third-round pick in that year's draft. 

Schultz helps the Pens win the Stanley Cup in June and piles up 51 points the following season while helping Pittsburgh capture a second straight title.

June 29, 2016: After the Oilers miss the playoffs for the 10th straight season, Chiarelli makes arguably the most perplexing move of his Oilers tenure.

Edmonton trades dynamic forward and future Hart Trophy winner Taylor Hall to the New Jersey Devils for defenseman Adam Larsson.

July 1, 2016: Two days after the Hall-for-Larsson swap, Chiarelli signs gritty winger Milan Lucic, 28, to a seven-year, $42-million deal.

Lucic posts 23 goals and 50 points in his first campaign with Edmonton, but his production sharply declines in subsequent seasons.

May 10, 2017: After making the postseason for the first time in 11 years and dispatching the San Jose Sharks in the first round, the Oilers lose to the Anaheim Ducks in seven games.

June 22, 2017: In yet another controversial June trade, Chiarelli sends forward Jordan Eberle to the Islanders for forward Ryan Strome. 

Eberle produces 25 goals and 59 points in his first season with New York. Strome manages 13 goals and 34 points in his first campaign with Edmonton.

Nov. 16, 2018: Chiarelli cuts bait on Strome, shipping him to the Rangers for Ryan Spooner.

Spooner's assigned to the AHL in January 2019, creating further embarrassment for Chiarelli on the Eberle trade tree.

Nov. 20, 2018: Chiarelli fires McLellan and installs Ken Hitchcock as the Oilers' new head coach. 

Edmonton missed the 2017-18 postseason under McLellan and went 9-10-1 in 2018-19 before his dismissal.

Dec. 30, 2018: Chiarelli trades Drake Caggiula to the Chicago Blackhawks in a package for Brandon Manning, who infamously injured McDavid in 2016. 

On the same day, the Oilers GM sends Chris Wideman and a pick to the Florida Panthers for Alex Petrovic.

Jan. 21, 2019: Chiarelli makes his final move as Oilers GM, signing goaltender Mikko Koskinen to a three-year, $13.5-million contract extension.

At the time of the deal, the 30-year-old netminder owned a .911 save percentage and had appeared in 31 NHL games.

Jan. 23, 2019: The Oilers fire Chiarelli following Edmonton's third straight defeat (all on home ice), a loss to the Detroit Red Wings.

Bob Nicholson takes control of hockey operations on an interim basis, and assistant GM Keith Gretzky assumes additional responsibility.
