I think it's a great signing. Has anyone seen Alfredsson not bring it? He's a competitor. Vinny doesn't if he doesn't want to. Alfredsson f***in brings it, every game. That's not a stat. He wants to win.
He will pick up in offensive production I would think. If you watch him play, as soon as he gets the puck he gets rid if it. He knows exactly where he's going as soon as he gets it, and after a while that will translate over into the offensive zone. He knows where his teamates are, the longer he's around the more familiar he'll get too. He may not pot 10 goals but I bet he gets a lot of assists, secondary assists.
I am very impressed with DeKeysers positional and defensive game but he seems to lack confidence offensively. He always looks like he is more worried about making a mistake and backs off early instead of getting in a good position to shoot or pinch in offensively.
The technical term for this is called "playing your position"
Also, I'd like to point out, everyone knows Philly is a scrappy team. Everyone knows if thet get fed up that someone on the Flyers will gladly hand their ass to them, or cheap shot them possibly. Even with all that info plain as day to everyone, that didn't stop Ryan White.
