Tanner Pearson had some golden opportunities in his Penguins debut, a 4-3 loss to the Lightning, but he wasn't able to capitalize on those chances.
Pearson debuted on the left side of the Penguins' first line with Evgeni Malkin and Patric Hornqvist. In 13:43 of ice time, Pearson didn't contribute in many ways that would show up on a scoresheet. He didn't score, and he was only credited with one hit. He finished with a Corsi For percentage of 58.33, or 10.19 percent better than the Penguins' performed when he wasn't on the ice.
The numbers aren't anything to fawn over. What else did he do?
