porro could do more yes but hes going away from it originally so momentum taking him the other way. hes probably seen johnson and thought subconsciously 'theres no need me to go into it hes right there'. then watched johnson pull away because hes scared of getting some physical contact from a professional sportsmen...johnson is to blame! cause: COWARDICE!
