2007-08: Played his second straight season with the Calgary Hitmen in the WHL. Collected 35 points, (10 goals, 25 assists) in 71 games played, all career highs in the WHL. Earned the reputation for being a consistent, smart, and unruffled rearguard.

His plus/minus took a hit, dropping to a +4, but Stone set career highs in goals, with 21, and assists, with 44. Stone added 20 points in 25 playoff games. He signed an entry-level contract with the Phoenix Coyotes(NHL) and is expected to turn pro in 2010-2011, playing with the San Antonio Rampage(AHL).
2010-11: Stone skated in 70 of 80 games for the AHL's San Antonio Rampage in his first pro season. One of three rookie defensemen to play a significant role for the Rampage, he was -5 with 2 goals and 11 assists and had 27 PMs. The Rampage finished four points out of a playoff spot in the AHL's competitive West Division.
2011-12: Stone made his NHL debut in February 2012, appearing in 12 regular season games and two playoff contests with the Coyotes after being re-called from AHL Portland. He scored 1 goal with 2 assists and was plus-seven with 2 penalty minutes' averaging just under 14 minutes of ice time during the regular season. Both of his playoff appearances came during the Coyotes second round series with Los Angeles; he was minus-two with no points or penalty minutes, averaging 11 minutes of ice time against the Kings. In 51 games with the AHL's Pirates he scored 9 goals with 13 assists and was plus-two with 24 penalty minutes. Portland finished third in the Atlantic Division; missing the playoffs by two points.
A smart two-way defender with good size and reach, Stone is a composed player at both ends of the rink. He is a strong puck-mover who makes a crisp first pass and can move the puck smartly and quickly up the ice. Keeps it simple in his own end relying on good positional and stick play.
Stone has made some nice strides in the Phoenix organization and his limited time with the club, including some playoff action, is a testament to his hard work. He will push for a spot in the top 6 but will be in tough again due to the team possessing such depth at the position.
