Throw Daniel or Henrik on a line with Chris Kunitz and Pascal Dupuis and see how many points they can rack up. They'd be lucky to reach 80.
FYI, Henrik was 1.1 PPG when he was playing without Daniel 2 years ago for those 15-20 games.
Interesting stat I found while checking up how many PPG he had, and here's the highest ESP/60 (even strength points per 60 minutes) since 2006:
