ahhh, another fan pet cat. I think everyone is fantasizing about Johnston. but lets not forget that that brand of football is no longer practiced in the NFL. the FB position has gone by the way side and we see less and less of them. with emphasis on the passing game, the two TE and spread offenses are what works in today's NFL>
so I am not as high on Copeland. he probably would only get 5-10 snaps a game anyway. outside of the youtube highlight videos of him blowing people up in the hole on running plays, the things I have read about him is his lack of proper technique as his approach is to try and decleat, instead of control and manage (ala Johnston). I am not sure about his pass blocking ability. also not sure how good he is catching out of the back field as everyone forgets how good Johnston was in that aspect of the game.
in short, its good to have pet cats. but I doubt if he makes it and the fantasies of him blowing people up through the whole and murray and dunbar running wild is, well fantasies and far from reality of today's NFL.
