I'm not blaming Rossi, or dissing him, I'm just saying that he hasn't used the time he's been given all that well, yet. It doesn't matter why. If his confidence is shot, he's not ready yet and more NHL time may only hurt it further. He didn't do anything wrong, but he also didn't do anything that was all that good, so if he isn't able to affect the play that much, he's probably not ready yet.
Or, maybe this was just a bad game, or he had jitters, and he'll improve from here out. Like you said, he hasn't had a long opportunity yet, so we don't really know. But if he needs Iowa time, he needs it. That doesn't make him a bust or anything.
