Blade wins...because as any martial artist can tell you, it doesn't matter how strong your opponent is, if you hit them in the right spots, you can drop them...Green Goblin's got pressure points, and vulnerable spots just like a regular guy, and Blade knows exactly where to punch or kick him to drop him to his knees...
Sure, the goblin's stronger, but that strength isn't going to do him much good when fighting an opponent that knows EXACTLY where to hit him to knock him down...it's like if Bruce Lee fought Dolph Lundgren...sure Dolph is stronger, but Bruce would know exactly where to hit him to drop him...
Now, if they were fighting with everything at their disposal and in their arsenals, then this would go different, but since they're fighting just H2H, then Blade takes it...
