I agree Barry Sanders was so much fun to watch and imagine if he had a O-line like Emmitt did. The players today are much better than in the past because they start training for the NFL when they are 6 years old, they have film study, they workout non-stop. To make the NFL now you have to be working for it your whole life, in the 50s, guys had part time jobs in the off season.
BTW can someone tell me why Terry Bradshaw is on this list? I know he won some Superbowls but was he that great of a QB?
