‘“I think you kind of saw a little bit of the old Zack in terms of, one, the physicality,” offensive coordinator Ken Dorsey said last week ahead of the game against Denver. “The first play of the game, he is hitting that thing downhill, lowering his shoulder, getting tough yards on a physical run. Then he comes back later in the game and he cuts one back and bounces out there, makes a guy miss and extends a run that maybe he might not be able to do last year. So I think you do see some of that stuff. It’s exciting to see kind of the health factor coming back.”’
