answer:It’s hard for me to reconcile “thinking” and “professional football”, but I’ll try. I think the Fox Sports dancing robot (the hyper-steroidized portrayal of an NFL player that they show on their game broadcasts) is pretty close to the mark. Future players will be more and more specialized in terms of size and strength. One day we’ll have 500-pound linemen, running backs who can do an under 4-second 40 yard dash with their pads and gear on, murderous cornerbacks who just happen not to have been convicted yet, and receivers who dance ballet in the off-season “just to keep in shape”. And the quarterbacks will be 7 feet tall, weigh over 250 pounds, able to keep pace with the running backs (they just can’t cut so well) ... and no one can touch them or they and their descendants will be banned from the League for life. And every single play will be reviewed as a matter of routine.
