Just because hes signs with the Blackhawks does not guarantee a spot on the NHL roster he still has to EARN a spot.
He is not big enough yet, he is no Sidney Crosby.
He is good but still has room for improvement, he needs to settle down when he has the puck and create not just try to razzle dazzle through traffic and lose the puck.
One player is not going to improve the Blackhawks, why not stay with a great team and try and win #8.
