First of all, he does play on the PP.
Secondly, he adds needed speed to this team. He moves the puck up ice as good as anyone here. I'd sure as hell rather have that than a guy who can simply be a "physical presence".
Thirdly, no one here knows how much he'll be re-signed for. You threw out a number of $2.5m a year, but just because you say that is how much he'll make, doesn't make it so. And even if it is, we'll have the space for him next year.
And lastly, it's a dick move to bump up this thread on his birthday just to be condescending about him.
