How many "Bobby Orr's" won club scoring titles?

[alko]

Bobby Orr won Art Ross Trophy twice.

but which ahnother defensmann won club scoring title?

[reckoning]

Ray Bourque did it 5 times in Boston ('85, '87, '88, '91, '92)

Denis Potvin did it his first 4 seasons with the Islanders

Brad Park in '74
Larry Murphy in '87
Sergei Zubov in '94
Paul Coffey in '95

There's likely many more examples. Pnep would have the complete list.

[Jungosi]

Dick Tarnstrom on the 2004 Penguins

On a serious note : Brian Leetch did it in 2000/01

[reckoning]

Can't believe I overlooked Leetch. He also led the Rangers in '91 as well.

Also Phil Housely in '91 and '92 with Winnipeg.

[TheDevilMadeMe]

Scott Stevens led the NJ Devils in scoring in 93-94.

Jan Suchy led the entire Czech league in scoring in 68-69 (in true Bobby Orr of Europe fashion).

[Dreakmur]

Art Duncan led the PCHA in 1924.

Bubba leading the B's five different times says almost as much about the Jacobs family as it does about him.
