Sorry if somebody's already detailed this but I hadn't seen it on the board yet so I figured I would share it with anybody who hasn't seen it. I'm currently listening to the 11 personnel podcast and they're talking about the abrupt switch at center. So far rodrigue has this to say:
Everybody in Rams can't was absolutely confident that Corbett would be the starting center. Then Brian Allen came along and repped really well against Dallas, to the point that people on the field were talking about him as the best offensive lineman on the Rams roster as far as standing out in the joint practices.
Jourdan is currently commenting about how Bryan Allen looks fluid, nasty, and tenacious. She knows that he looks a lot stronger than he did his A couple of years ago as well. I'll keep updating as I continue.
