Colaiacovo registered an assist in Tuesday's 2-1 win over the Stars. Colaiacovo is not contributing heavily on offense this season. In 20 games, the defenseman has four assists and zero goals, despite setting 10 shots on goal over the past five contests. Colaiacovo had 20 or more assists in three consecutive years with the Blues between 2008-11, but that seems like a distant memory at this point. Past injuries to his leg and upper body have not helped Colaiacovo's chances to be productive.
