"For him, the sky is the limit," Choice said of Gibbs. "I'm going to push him. I'm going to push him like no other. I have to.
"Having the chance to watch (Gibbs) from afar for these last three years, and every single week because of (Lions defensive coordinator and close friend Kelvin Sheppard) Shep and because of Jah, I kept wanting to watch the Lions' games.
"To see him progress, to see how smart he is — I tell him he's one of the smartest running backs I've ever coached. He's just a natural football player ... so having an opportunity to get around him now coaching, I'm going to be harder on him even more."
Gibbs was third in the NFL last year in average yards per carry (5.65) and had the highest percentage of 10-plus yard runs in the league (16.4 percent). He scored a touchdown in 13 games.
