I think Stevenson would offer us more in that position than Craig everytime. I think he's more capable of getting to the byline and causing problems. But he's not able to do that at the moment, because running the full length of the pitch back and forth for 90 minutes, is zapping all of his energy.
LC has shown that he's incapable of taking players on. I haven't once seen him turn a defender to get himself into the box or to the byline. Instead, he lumps the ball into the box from about 40 yards, hoping for some miracle to happen.
