One of the most significant criticisms of Brian Boyle in his time with the New York Rangers was that he would not play in an enforcer’s role. That would not change if he came back to New York, but the Rangers would need to understand that enforcers are not significant to success.
Boyle fit seamlessly in New York before, and the towering center would do so again. Boyle is a fantastic possession player who can be sneaky good offensively. Defensively he is among the top fourth liners in the league, and the Rangers already know what he can bring to the table.
The main concern is that the rest of the league also knows how good Boyle is, but at the right price he would fit well on the fourth line.
