They can correct me if I'm wrong but I'm pretty sure the posters saying why doesn't someone cover Ovechkin on the powerplay are joking, unless they actually believe he just stands in the same spot the whole time and no one pays attention to him which I somehow doubt, lol.
I don't think a lot of them are joking. The game media regularly comments about how open Ov seems to get where everyone knows he will be. I am sure for those that don't watch him every game that its the case. That teams don't game plan him on the pp. Its understandable.
The reality is that teams have shadowed him on the pp. Ovechkin then takes himself and his shadow out of the play and the Caps go 4 on 3 which is easier. Last season teams made a concerted effort if not to shadow him, to stand a pk player in his shooting lane at all times. That was the case last night when he scored. There was a guy right there. The shot didn't hit him and created a screen.
Facts are that teams do the best they can to stop the Caps pp. Its hard. There is a reason Ovechkin may be the greatest goal scorer of all time. There is a reason that Backstrom may challenge for the best passer of all time. They are good. Then there is Carlson who most here wont even put in their top 20 defensemen. He is good.
