Personally, I think he was in because on the first rushing play of the game (I think) Breece was out of position and it was a discombobulated mess. Purdy and Campbell were both not happy. After Breece's long run, Campbell was calmly talking to him. I may be reading too much into it but it appeared to be a "this is what you can do with your head in the game" moment.I think he gets that one series early to try to prove himself and if he doesn’t get anything with it, he’s pretty much done for the day.
