But what if Jackson, with his once-in-a-generation elusiveness and acceleration and a creative ground attack tailored specifically to his skills, is the man to turn that logic on its head? Opponents know what’s coming at this point, and after 14 regular-season games, they haven’t stopped it. The Ravens’ week-by-week rushing totals have become sort of numbing: 265 yards, 182 yards, 203 yards, 269 yards, 199 yards. Each would represent a season best for many teams. The Ravens’ worst number of the season — 138 yards in a Week 5 win at Pittsburgh — is better than the weekly average for all but four other teams.
