Maybe it's obvious, but Ameer Abdullah had his most efficient game running the football in last week's win over the Minnesota Vikings.
Adullah set career-highs in yards (94) and carries (20) as the Lions built their offensive gameplan around him as a way to control the clock and keep the Vikings' tenacious defensive line away from Matthew Stafford.
The NFL measures "efficiency" in running backs by tracking the total distance a player covers on rushing plays per rushing yards gained.
The lower the number, the more north-south a runner is, and thus — in theory — the more efficient.
