Chris Tierney has been in the Sharks organization since he was drafted 55th overall in 2012. He played two seasons with the OHL’s London Knights after he was drafted. In 2014, he had a short stint with the Worcester Sharks (where he scored 29 points in 29 games) before being called up to the Sharks, where he has played all but two games since.
Tierney spent time centering both the third and fourth lines for the Sharks this season, and unsurprisingly had more success with his linemates (Joel Ward and Patrick Marleau) on the former. We did a post about his production with various linemates a couple months ago that you can read here.
