The fourth line that New York Rangers carried into the 2014 Stanley Cup Finals consisted of Brian Boyle, Derek Dorsett, and Dominic Moore, with Daniel Carcillo rotating in from time to time.
The biggest key to these four players game was their ability to bring a physical, hard-nosed forecheck, wearing opponents down and even contributing with a big goal sometimes. They were a line that was expected to score, but not due to lack of effort.
By the end of the regular season Boyle, Moore, Dorsett, and Carcillo accounted for 19 of the Rangers goals, while collectively contributing 47 points.
