Lynch is not more talented, only more powerful. He is not more elusive, he is not a better blocker, he is not a better receiver, he does not read his blocks as well, he's not as well conditioned, and he doesn't make smarter decisions on or off the field.
Power is just one aspect of the game. Lynch can move a pile better, can lower the boom better when he gets a head of steam going, but other than that he does nothing better, and Bucky is right to say he, rather than Freddie, is who should be the change-of-pace and short yardage back off the bench.
