i both agree and disagree here.
i think because of the skill set Josh possesses, he presents a unique problem for defenses. has a strong arm and an equally strong run threat. what i see from the looks of the last two games and the Miami game in particular, is that Josh has absolutely no problem with passes of 20+ yards or more. this means that defenses have to respect that. drop threat out of the backfield into the flat on one side and what that does is essentially clear out the field underneath, from the D-line to the depth of the CB's. if the receivers are covered, he has the option of hanging a 10/15 burger on them with his feet pretty easily, if not more. if they spy him then that leaves one less man to cover the receivers.
obviously he is still a rook and has a ways to go but he should develop both of these aspects to a greater degree and become more lethal as experience comes.
i am going to be real curious to see the game in NE, see what belly boy tries to contain him.
