One thing we know for sure about the 2018 Dallas Stars is that dumping the puck into the offensive zone and forechecking were a focus. Going by the data tracked by Corey Sznajder the 2018 Stars ranked 29th in Carry in %, 31st in Pass In %. and 25th in Shots Off Entries Per Game, and 21st in Shots Per Carry In. They dumped the puck.
A lot.
Were they actually any good at it though?
Ryan Stimson of The Athletic NHL recently wrote a great piece about forechecking across the league using the same collected data referenced above.
