re: What does Derrick Henry need to do to make the HoF?

Realistically, he needs three more 1,700+ yard seasons. Will his body hold up? Maybe four 1,300+ yarders; it puts him comfortaby around 12K yards, around or above 100 TDs, probably another Pro Bowl or two, and still in the general conversation for the best back over a period longer than 3 or 4 years.
