He has a decent first-pass, but in the offensive zone he's been really inept this post-season.
I mean, I don't mind it since he's upped his defensive game back to his standards (after a poor Nashville series), but I still think it's a joke that he's on the 2nd PP unit. He's not a threat at all and it looks like it's making it harder on the forwards since the Blues can completely ignore him on the blue-line. I think Polak has looked more like an offensive threat jumping into the play and cycling the puck.
I disagree with you. I think his major offensive deficiency is power behind his shot. He's shown plenty of times he has decent shot placement, but he just can't be a cannon from the blue line. Plus his passing, and puck control are quite good.
However the first key to scoring, is having the puck, and Vlassic is one of the absolute best defenseman in the entire league at keeping the puck moving in a positive direction, while minimizing the oppositions chances, thus leading to more offensive zone time, thus more chances to score.
Vlassic had 40 pts in 67 games, there is no way that a truely terrible defenseman gets that many points,and his 5v5 p/60 is even better. Plus you can add on the fact that he gets horrible zone starts, and is constantly playing the other teams best players, and there is no question that Vlassic is perfectly capable of being much better than a 20-25pt defensive defenseman.
He's not an offensive Dynamo like Burns, but he's much more of a Two Way defenseman than he's been giving credit for.
