After playing 20 matches in 2013, Kostjasyn upped that figure to 25 this year, only missing the round 17 clash against St George Illawarra due to a painful rib cartilage injury.
He started the season with three matches as the Cowboys’ bench dummy-half but then took over the starting role in round four against the Titans.
From then on, coach Paul Green kept his faith in the 27-year-old who rewarded him with solid performances every week.
Tireless in the middle of the field, Kostjasyn’s tackles per game count ranked fourth amongst all Cowboys.
WHAT’S IN STORE IN 2015:
Incumbents Kostjasyn and Thompson will face good competition for the dummy-half starting and bench roles next season with Cameron King set to return from his season-ending ACL, Jake Granville joining the Cowboys from Brisbane and Josh Chudleigh stepping up from the NYC squad.
Kostjasyn’s talents mean he could also be in the mix for a back-row slot.
