He skates very quickly to get into position to receive the puck (Hull couldn't do that very well) and he occasionally takes the puck away from the opposition. (Hull didn't care to learn how to do that till he started playing in Detroit under Bowman.)
As an entertaining human-being, nobody beats Brett Hull.
There was a time during the Mike Keenan-era in St. Louis where Brett Hull was told by Keenan to serve the 2-minute bench minor. Hull, ever the moody super-star, was none to pleased having initially told Keenan, "I don't kill penalties". After being ordered to the sin-bin anyway, the Blues managed to kill the entire 2-minute penalty, and as it happens just as the penalty expires, the Blues defenseman clears the puck up the ice to the vacated penalty-box just as Hull stepped out...essentially springing Hull for a would-be break-away. Instead, Hull steps over the puck and lets the puck go the length of the ice for an icing call, and as he gets to the bench he stoically says to Keenan, "I told you...I don't kill penalties".
