If you said that the Bruins top line looked great in Monday's win over the New York Islanders, you'd be correct. What would not be clear is just which line you were talking about.

As of now, the B's boast two lines that are playing like top units.

The Brad Marchand-Patrice Bergeron-Tyler Seguin trio, now together for five games, could have some staying power. It only produced one goal in the 6-2 win over the Islanders — Seguin's — but left at least two or three more out on the ice. From the drop of the puck, you could sense the 17,565 at the Garden sliding to the edge of their seats every time the trio stepped on to the ice.
