Bush is a one dimensional specialist. The Canucks knew it too, every time he had the puck they backed off because they want him passing and not someone better. I like him as a 7D but Capo will be the better everyday player.
He's not really 1 dimensional, Boosh lacks the dimension of exiting his zone cleanly. Don't see many long tape-to-tape passes through the neutral zone to beat the forecheck from him right now. But once he's in the offensive zone he holds the line and distributes the puck, even has some ability to get the puck on net. I feel like he's had a point in every preseason game so far which doesn't mean a ton other than there's more offensive talent then you might think from a dude who will gladly play the body as much as he does.
Hopefully the zone exits come when he gets more NHL minutes since he already seems more capable with the puck this year.
