No. 36: They're old school

The Ravens have stubbornly stuck by the run, recognizing that ground-and-pound is essential to winning in the post-season. Vonta Leach is one of the last fullbacks in the NFL -- a position that's going extinct in an era of pass-happy football. At 6 feet, 260 pounds, he's a beast, known for throwing vicious blocks and even catching the occasional short pass. Third-and-goal with one yard to go? Send in Leach.
