Warsofsky, a disciple of Penguins’ Sullivan, ready to lead Sharks

SAN JOSE – Ryan Warsofsky remembers sitting in Mike Sullivan’s office as a teenager and disagreeing with the then-Boston Bruins coach about a certain defenseman on the team. Sullivan liked him, and Warsofsky — not one to back down — said he didn’t.

“That was probably the first moment I’m like, ‘I love this,’” Warsofsky said of catching the coaching bug from Sullivan, a longtime friend from his hometown of Marshfield, Massachusetts now in his 10th year of coaching the Pittsburgh Penguins.
