Again, a good point, but I don't think YPC is the ultimate stat for rushing. That being said, I think 1)a lot of this was due to our leaning on the rushing game, 2)also partially due to injuries, 3)we were only 46th in total rushing yards, tied for 30th in TDs. You've pointed out last year was a down year, I think largely due to injuries up front, and the above average number of carries that we have (ranked 32nd).
It also gets weighted down pretty heavily when you have a QB with cement feet and the sack yardage therefore being deducted from the total.
It could also be a disappointment. The OL is shallow, the wideouts average, the quarterbacks are unproven, shallow at TE . . . lots of question marks on offense. We are not even deep at running back any more.
As in the same offense....hopefully Cam comes in and throws Miles in a straight jacket when we've got the ball, makes him his offensive cuckold and only lets him out to recruit and oversee the O-Line. I love ya Daddy Miles but its time to adapt.
