Moss is definitely the most physically gifted wide receiver in the league. However, Marvin Harrison is also an excellent WR. It would be a tough decision between the two, but I would go with Harrison. He doesn't have his size but he is the most productive of the bunch. I know that he does have a great QB throwing to him, but that isn't what makes him great, and remember that Moss doesn't exactly have a bad QB throwing to him either.
