One reason to the early success of the Sharks may actually be Larry Robinson, perhaps the greatest defensive coach in the entire NHL?
Probably the best move the Sharks have made in a long time.
It may also explain why a guy like Douglas Murray is playing a little bit more polished game instead of trying to crush everything in his way.
I read in a swedish interview Murray praising Robinson.
I think that along with the fact that the Sharks addressed concerns with defensive depth (a huge concern last season) by re-acquiring Brad Stuart has helped them immensely. Now they need to address their forward depth problem, which they did somewhat with Gomez. Robinson should be able to help with him as well.
