He seems to kind of fighter that might cause Lemieux problems. Stevens is agressive, a decent puncher, and tough enough to at least stick in there until the later rounds. Lemieux seems the sort of fighter who might have trouble with the sort of aggression and pressure Stevens brings.
I think the odds are abit to wide but Lemieux is the favourite and will probably stop Stevens. With that being said at those odds Stevens is worth the punt just incase the lemieux is weight drained or out of form like in his last fight.
