HAVERHILL — On Sunday, Claude Julien was back behind a bench.

It was at Haverhill Valley Forum, not TD Garden. Julien’s charges were 13 boys from the Winthrop Squirt B youth hockey team, not Zdeno Chara, Patrice Bergeron, and Tuukka Rask. Julien was wearing a Bruins jacket instead of his usual suit and tie.
