re: Besides AP what active RBs do you think will be a future HOFer?

None of these guys will play as long as Frank Gore. They are all ball hungry featured RBs in balanced offenses with big armed QBs...mostly. Take any one of these guys and put them in a Greenbay or New England type offense and they're production would be squandered. AP will get in because he benefited from playing in a very run heavy offense and was the best option. Throw back type of guy. Marshall Faulk and Ladainian Tomlinson were also featured backs but caught a heck of a lot of footballs and scored a ridiculous amount of TDs. Today, this type of production for the most part is accomplished using multiple backs in pass heavy offenses.
