After years of eschewing the draft in favor of pursuing veteran talent, the Leafs have finally changed gears and started to rebuild their prospect system under much-maligned general manager Brian Burke.
Traditionally, the title of "difference-maker" is bestowed upon a player who is expected to make a quick, noticeable impact once he graduates to the NHL, in a statistical sense.
However, there are numerous ways in which a player can make a difference in hockey. From blocking a shot to agitating opponents, there are various ways in which a player can influence the outcome of a game beyond the score sheet.
Currently, the Leafs don't possess a difference-maker in the vein of a player who the franchise can build around (think John Tavares or Ryan Nugent-Hopkins), but they do have multiple prospects who will be able to make a difference at the NHL level in one way or another.
