Interesting article - Top 25 NFL power RBs of all time
 

Kind of surprised Big George wasn't listed in the lower tier of RBs here. His numbers compare favorably to William Andrews and Ironhead Heyward. Guess he is often overlooked because of the injury and substance abuse issues that cut his career short, but at 6'2, 230 lbs., he definitely inflicted some damage in Bum Phillips' Saints offenses.

Selecting the greatest "power backs" in NFL history is an inherently difficult task because of one main problem: How do you define a power back?

Does that phrase call to mind someone like a Lorenzo Neal, perhaps the greatest blocking fullback ever, who accumulated minimal rushing yards? Or how about a Natrone Means, a plodding 245-pound behemoth with 5,000 career yards?

For the sake of the top 25 list to follow, "power back" refers to a player who inflicted as much or more punishment on defenders as he received. This is not a ranking of the greatest all-time backs, though many of the names you'd include there are in the mix here as well.

This is an appreciation of those who opted not to run out of bounds, lest they give up an extra yard or two. The top 25 power backs in NFL history.
