General managers, coaches and analysts alike have touted this year's running back class as one of the best in recent history.
The Lions could be in the market for another runner to pair with Ameer Abdullah, Theo Riddick and others currently on the roster.
Leonard Fournette (LSU) and Dalvin Cook (Florida State) are the cream of the crop, and have been given grades in the 90's (out of 100) by Scout's Inc.
A player with a grade of 90-plus is described by the scouting service as: "A player with rare abilities and can create mismatches that have an obvious impact on the game. Is a premier college player that has all the skill to take over a game and play at a championship level. He rates in the top 5 players in the nation at his position and is considered a first round draft prospect."
Alvin Kamara (Tennessee), Christian McCaffrey (Stanford) and D'Onta Foreman (Texas) all have grades in the 80's.
Those prospects given grades in the 80's are described as: "Player has abilities to create mismatches versus most opponents in the NFL. A feature player that has an impact on the outcome of the game. Cannot be shut down by a single player and plays on a consistent level week in and week out. He rates in the top 10 at his position and is considered a second round draft prospect."
So what sets these five players apart? Who is the best back in the class? Each made their case Thursday at the Combine.

**ALVIN KAMARA, TENNESSEE

D'ONTA FOREMAN, TEXAS
HT/WT: 6-1, 249
2016 stats: 11 games, 323 carries, 2,028 yards, 15 touchdowns, seven catches, 75 yards, no touchdowns

What sets him apart: "Just because of my size and my speed. Fournette is a big back too, a lot of speed and power, but I just feel like I'm different. My mindset is different. When I go on the field, I want to be the best.
"I told myself coming into the season this was going to be my year to really show people I was one of the best at my position and I feel like I was able to do that. I still feel like I'm one of the best and when I get out there I'll be able to show I'm the best."
