The Detroit Lions made several moves this offseason to address a stagnant run game that has ranked dead last in the NFL in two of the past three seasons, and hasn't produced a single-game 100-yard rusher since 2013.
LeGarrette Blount was signed, and Kerryon Johnson was drafted to add more talent to the Lions' backfield, and the team used its first-round draft pick to select center/guard Frank Ragnow to beef up its offensive line.
Is it enough? No one will know until the Lions start playing actual games. And, on paper, ESPN's NFL backfield rankings posted Friday (pay site) suggest the Lions might still have some work to do.
