The Sharks have struggled on the power play, dropping to 19th in the NHL. Joe Thornton scored 33 points on the power play last season, but has just seven so far this season. “I think Jumbo would like to have more production there and he’s the focal point. It’s his power play,” coach Todd McLellan said Friday. “It runs through him, but there are other pieces in the mix and they have to be productive.”
