The problem is that if Franzen isn't scoring goals, he doesn't bring anything else to the team.
He needs to be more aggressive offensively and always look to shoot first. That doesn't always seem to be the case. We've seen him go on streaks where he's as good as anyone in the league at scoring goals. When he doesn't do it consistently, it appears it's because of him having a lazy work ethic.
The converse argument is when people state that he produces at the pay level he's currently at. I guess that's true. But that doesn't mean it's OK for a guy to be lazier and underachieve a bit.
