To put things into perspective, Jurco played every game in November of last season and scored 1 goal and 1 assist. He also played every game in February and scored two goals. That's 24 games, in two 12 straight game segments. So while I agree that he's seen spotty usage at times, he's also seen prolonged usage at times as well. In neither case has he produced to the extent that he should given his skill set. He may need more time, and maybe he'll get it, but he's been undeniably disappointing thus far in his career.
For comparison's sake, Teemu Pulkkinen played every game in October a scored 4 goals and 2 assist, and every game in November and scored 2 goals and 3 assists.
Another issue is that most of the roster had bad years as far as production goes. Outside of Larkin and Abdelkader, it's been a disappointment all around (only counting players on the team all season). Nyquist and Tatar were invisible for long stretches during the season.
Hell, even Abdelkader took a couple seasons to start producing playing with Pav and Hank. His production early on playing with those guys was not good. Yet the coaches always stuck with it because he brings more to the table than just putting up points. I don't think it is at all unreasonable to think that Jurco can have a similar impact on the team given some consistency in the lineup.
