He has previously played for the Oilers, New Jersey Devils, Arizona Coyotes, Buffalo Sabres, Boston Bruins and Chicago Blackhawks.

Hall had a highly successful junior career, helping the Ontario Hockey League (OHL)'s Windsor Spitfires to two consecutive Memorial Cup championships in 2009 and 2010.

[1] His mother introduced him to organized hockey at age five while his father maintained a backyard rink every winter which Hall and his friends practiced on relentlessly.

[5] For the 2005–06 and 2006–07 seasons, Hall played Bantam and Minor Midget hockey for the Greater Kingston Predators of the ODMHA league.

[5] After the season, Hall was the second overall choice in the 2007 Ontario Hockey League (OHL) Priority Selection by the Windsor Spitfires.

[5] He scored the game-winning overtime goal in the fifth and deciding game of the OHL Finals against the Brampton Battalion to clinch the title.

[5][10] Though the odds of him playing in Russia were remote, Hall was drafted 89th overall by the Kontinental Hockey League (KHL)'s Ak Bars Kazan on June 1, 2009.

[11] Hall was an early favourite to be the top pick in the 2010 NHL entry draft since entering the junior ranks.

He was praised early in his junior career on Hockey Night in Canada by commentator Don Cherry during his "Coach's Corner" segment.

[14][15] Hall was instrumental in the Spitfires' 2010 J. Ross Robertson Cup championship, recording a playoff-leading 35 points in 19 playoff games.

With the victory, Hall was awarded his second-straight Stafford Smythe Memorial Trophy as tournament MVP (the first player in its history to repeat as a winner), the Ed Chynoweth Trophy as Memorial Cup scoring leader and a spot on the tournament all-star team for the second-straight year.

[19] Hall has cited Toronto Maple Leafs forward and 2009 NHL entry draft first overall pick John Tavares as a role model, both on and off the ice.

[20] Shortly after being selected first overall by the Edmonton Oilers in the 2010 NHL entry draft, Hall signed his first professional contract.

The contract paid Hall the entry level maximum of $900,000 with the potential of an additional $2.85 million in performance bonuses.

[23][24] Hall made his NHL debut on October 7, 2010, as the Oilers defeated their Battle of Alberta rivals, the Calgary Flames, at Rexall Place.

On October 17, 2013, Hall broke Wayne Gretzky's previous Oilers franchise record of two goals in nine seconds by scoring two in eight.

[36] On December 5, 2013, in a 9–2 win over the Chicago Blackhawks, Hall recorded his second career NHL hat trick,[37] having previously gone nine games without a goal.

[49] Hall again led the Devils in the playoffs as their top scorer with six points (two goals and four assists) as the team was eliminated in the first round by the Tampa Bay Lightning, four games to one.

[50] The following day, on April 27, Hall was also declared a finalist for the Hart Memorial Trophy as the NHL's most valuable player.

[55] Despite these injuries, Hall was selected for his fourth consecutive All-Star Game,[53] but was later replaced by teammate Kyle Palmieri as he had not yet recovered.

[66] On May 17, 2021, Hall recorded the tying goal against the Capitals to send the Bruins to overtime in Game 2 of the first round of the Stanley Cup Playoffs.

On July 23, 2021, Hall opted to forgo free agency by agreeing to a four-year, $24 million contract extension with the Bruins.

[67] Hall had a successful first full year with the Bruins, scoring 20 goals and 41 assists, totaling 61 points, his highest since his MVP season with New Jersey.

However, the season would end in disappointment when Hall and the Bruins fell to the Florida Panthers in seven games in the first round of the Stanley Cup Playoffs.

On June 26, 2023, due to salary cap implications, Hall was traded by the Bruins along with Nick Foligno to the Chicago Blackhawks, in exchange for Ian Mitchell and Alec Regula.

Hall was invited to Hockey Canada's summer evaluation camp for the 2011 World Junior Tournament, but declined to participate, choosing instead to focus on making the Edmonton Oilers' roster for the upcoming NHL season.
