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. He was one of three Canadian junior players (all from
the OHL) taken in the 2009 KHL Draft, which begins selecting players a
year younger than the NHL does. 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. He was also featured in a July 2008 issue of Sports Illustrated, profiling young athletes poised to star in their sports.

NHL Central Scouting Bureau (CSB) in its 2009–10 midterm rankings.

New York Islanders forward and
2009 NHL Entry Draft first overall pick
John Tavares as a role model, both on and off the ice.
Shortly after being selected first overall by the Edmonton Oilers in the 2010 NHL Entry Draft,
Hall signed his first professional contract. The contract pays Hall the
entry level maximum of $900,000 with the possibility of an additional
$2.85 million in performance bonuses. This is the highest rookie contract in Oilers history.
Hall was given permission to wear the jersey number 4, which had belonged to former Oilers' player Kevin Lowe,
who was then serving as the Oilers' President of Hockey Operations and
who had been the only Oiler to wear the number 4 in its NHL history.
Hall made his NHL debut on October 7, 2010, as the Oilers defeated arch-rivals, the Calgary Flames at Rexall Place. Hall's first NHL point, an assist, came in his second game, against the Florida Panthers on October 10, 2010; Shawn Horcoff redirected Hall's shot in front of the net. His first NHL goal came on October 28, 2010, against Steve Mason of the Columbus Blue Jackets and his former coach with the Windsor Spitfires, Bob Boughner.

rookie season early as Hall suffered a high ankle sprain at the end of
the fight. Hall finished his rookie season scoring 22 goals and 20
assists in 65 games.
Hall recorded his second career NHL hat-trick in a 9–2 victory over the Chicago Blackhawks after going nine games without a goal.
On January 17, 2012, Hall was cut by teammate Corey Potter's
skate before a game against the Columbus Blue Jackets during warmup,
resulting in a deep cut to his face that required 30 stitches to close.
