Bad balance and he lacks power to finish runs. Has deep speed, but is more apt to run up the back of a blocker than find the hole and break it.
The comparisons to Murray are way way off.
He's basically a Darren McFadden starter kit.
Yup, that is exactly what I see - Darren McFadden lite.
He's not as naturally gifted as McFadden, but their running styles are similar and they share a lot of the same strengths and weaknesses.
What do you thin of Duke Johnson? Nothing about him jumps out at you, but that's not a bad thing necessarily. I like my RB's to be dependable and consistent, and I think he's got that.
He's got enough acceleration and speed to get big yards, but he's got solid strength as well. He's good between the tackles and has very good vision, as evidenced by the significant amount of cutback runs against the grain that he turns into big gains.
After Ayaji, this is who I would take because there's no gimmicks with him. He's just your standard, dependable back who can work very well behind this line.
