It doesn't sound like much for an NFL running back, but as one of Frank Gore's oldest football friends says, “He doesn't look like much.” When it comes to Frank Gore, there isn't a ready image of him pulverizing defenders like Marshawn Lynch or leaping over would-be tacklers like Earl Campbell or breaking ankles like Barry Sanders. What there is, though, is that 4.4 yards-per-carry average – which is more than LaDainian Tomlinson averaged, more than Curtis Martin, more than Emmitt Smith, and the same as Walter Payton carried over his legendary career.
