First and foremost, your generosity in putting this video together is always much appreciated.
Secondly, I can't help but notice a couple of things:
1. On many of Julius' big runs, the yards weren't gained by running through the designed run. This is a combination of a couple things:
a. Julius has great vision as a rookie. He's not running scared and knows that there's more ways than one to skin a cat.
b. For only being his third game, he has great anticipation of his lineman's blocking.
c. The WR's are blocking very physically and well, helping to spring Julius from 7 yard runs to 13 yard runs.
d. One thing that separates Julius from Emmitt, I believe Julius' acceleration, agility and top speed are significantly better. In the upcoming games, I'd like to see if Julius' balance and catching ability match/surpass Emmitt's.
