Dumba hasn't ever been good in Ovi's spot, or on the PP in general. His best numbers are 6ppg (3 times), 10 ppa (once), and 12ppp (4 times). He has the big shot, but it's so inaccurate that it misses the net way too often. There isn't even a chance for a dirty/rebound goal because the puck is headed out of the zone. The Suter limp wrister was so much better at creating scoring chances, as a counter point. Spurgeon isn't much better either, his 14ppp this year was a career high.
The whole pp setup needs to be reworked. They need to move the puck, not just sit and hold it or play hot potato between the halfwall and the point. This is nothing new it has been a problem for years. The entire PP (except Spurgeon) has changed over for the Coyle, Granny, Koivu, Nino, Parise, Suter years, yet it's the same slow and methodical approach. It leads me to believe it the coaching/system not the players that are the issue.
