ST. JOSEPH, Mo. — At some point this season, likely within the first couple of games, Jamaal Charles will slide past Larry Johnson and breeze past Priest Holmes to become the Chiefs’ career rushing leader.It’s a goal, sure. But it’s only a rest-stop on the way to loftier expectations.After arguably the best season of his career and now armed with a new contract extension, Charles has his sights set on the Hall of Fame. The two-time All-Pro running back wants his name to be mentioned in the same breath as Emmitt Smith and Barry Sanders, players he grew up idolizing in Port Arthur, Texas, and who will forever be considered some of the best to play the game.“It’s all about staying consistent,” Charles said.
