2009-10: Ryan Sproul played for two OJAHL teams during this season. In 7 games for the Bramlea Bulls, he picked up 1 assist. In 8 games for the Vaughn Vipers, he scored 1 goal and added 1 assist for 2 points. Sproul was chosen in the fourth round, 49th overall, of the 2010 USHL Entry Draft by the Tri-City Storm.
2010-11: Sproul began the season with the Vaughn Vipers, but joined the OHL's Sault Ste. Marie Greyhounds after 3 games with the Vipers. In 61 games for the Greyhounds, Sproul scored 14 goals and added 19 assists for 33 points.
2011-12: Sproul signed an entry-level three-year contract with Detroit in March 2012 following his second junior season with Sault Ste. Marie. He was the third-leading scorer for the Greyhounds and was third amongst all OHL defensemen with 54 points. He scored 23 goals with 31 assists and was plus-16 with 53 penalty minutes in 61 games for the Greyhounds. After a tight three-team playoff race down the stretch, Sault Ste. Marie finished fifth in the West Division, one point behind Windsor for the final spot.
Sproul considered playing in the NCAA before finally deciding to play major-junior hockey with the Sault Ste. Marie Greyhounds. He boasts an impressive shot from the blueline and solid offensive instincts. If he can fill out his 6’4 frame and assert himself physically, Sproul could turn into a solid two-way defender, reaching as high as a 3rd or 4th on the defensive depth chart.
Sproul will build off of a successful 2011-12 campaign in which he led all OHL defensemen in goals. He will play one more OHL season with Sault Ste. Marie before likely joining the AHL's Grand Rapids Griffins in 2013-14.
