Going through game notes for OU game and the amount of changes on the official depth chart caught me off guard. You just do not see coach Snyder make much changes once season starts even injured starters stay in their place. I will post links below so the two can be compared. The two changes I found the most interesting with the first being the most, Barnett is now no longer listed, only time it seems like Snyder changes starter at depth chart and team leader at that is if the injury is season ending (I.E. Ertz, Britz last year). I might be wrong on that assumption but just throwing that out there. Second change is Davidson replacing Delton which falls in line with the same thinking like Barnett. I know they were considering sitting him rest of year even though he might be able to come back. There are other smaller changes we already know (RBs, Reuter, etc.) but was surprised just by all the changes.
