It’s possible that Vincent Brown just needed to get comfortable with the offense before he started producing. He might have needed the experience from his first season in the offensive system in order to get a better understanding on the plays and of the offense.
Maybe he just needed to study his playbook a little more. There were a number of times that he was on a different page from Philip Rivers last season.
Whatever he needed, it sounds like he was able to make a step forward in his progress. From the reports out of OTAs, Brown looks more confident in his routes and he is looking forward to making an impact this season according to ESPN reporter Eric Williams. The report even mentions that Brown is pushing Keenan Allen for minutes.
