The Lions are just more than a month away from the start of the first training camp of the Matt Patricia era. The roster mostly is what it will be this season, short of when it shrinks to 53 men by the start of the year.

It'll be up to the new coaching staff to get the most out of what it has, but what exactly does it have?

In the coming weeks, I'll have my own grade of the talent the Lions are working with at each position group on the roster. But this early in the NFL's dead period, we want to hear from you.

This is the second of a series of polls grading the different position groups on the Lions roster. Now up are the running backs.

Theo Riddick is the established piece in Detroit's offense, as he's mastered the third-down receiving role to the tune of at least 50 catches in three straight seasons. Like all Detroit running backs, he hasn't caught on nearly the same as a runner. He finished last season with 286 yards and three scores on 3.4 yards per carry.

Ameer Abdullah enters a critical contract year after his first three haven't seen the production his second-round draft slot suggested. He ran for 552 yards and four touchdowns on 3.3 yards per carry last season.

This offseason featured a bit of an overhaul to this group, starting with a one-year deal for LeGarrette Blount. At 250 pounds, the 10th-year pro is an established power back who played that role on Super Bowl-winning teams for the Eagles and Patriots the past two seasons.

Kerryon Johnson is also new to Detroit after the Lions traded up in the second round to take the Southeastern Conference's leading rusher out of Auburn. He brings a variety of developing skills and will fight to carve out a role this year.

Zach Zenner and Dwayne Washington will fight for a roster spot, and former linebacker Nick Bellore has been getting work as a fullback after some spot duty last season.

The group in general is looking to produce the first 100-yard rushing performance in four years in Detroit and finish out of the bottom 10 for the first time in that span as well.

How do you grade the position group?
