Lamb has had his moments.
The 5-foot-9, 210-pound Lamb took a Teddy Bridgewater screen pass 53 yards to the house in a loss at Syracuse during the 2012 season and last year gave U of L the lead for good with a 97-yard kickoff return in the opener against Miami.
But Lamb has seen his career riddled by injuries. He has had his season ended early the past two years with a torn ligament in his knee, including after eight games last season.
Lamb is back for the Cardinals and head coach Bobby Petrino said recently he "looks really good. He's so fast."
With a lot of depth at running back, Lamb could see a few carries out of the backfield and will be used as a slot receiver to get the ball in his hands. He'll also be used as a kickoff returner for the Cardinals.
"He's fast and can really help us out," special teams coordinator Tony Grantham said. "He looks really good."
Clocked as the fastest member of the Cardinals roster, Lamb returned six kickoffs with a team-leading 31.2 average per attempt last season. He has three career TDs and suffered a torn ligament in the opener two years ago.
