break-away runs. Harvey just isn't as fast as Jamaal and therefore his big runs were for 10-20 yards, where as if you give Jamaal that much open room, no one can catch him. I sort of feel like Unga was actually a better running back, but Jamaal is the better true athlete. Unga fought for most of his yards and rarely left us short. I don't have that same feeling with Jamaal yet (though it's really close). I think Jamaal is much more explosive and overall will end up with more yards, but I just remember watching Unga lower his shoulder and bury DB's. In reality, both are amazing RB's that I am grateful to have.
If you give me 3rd down and short, I would take Unga every day and twice on Sundays. But overall, I think that Jamaal has more upside because of his speed and I think will easily end up with more yards.
