You know, I want to point out something here. That was a great job by Meredith to contain and hold up D-Rob in the backfield for a bit. Obviously Rob is elusive enough to get out of a tackle there, but the point is he delayed him and allowed help to get there.
I have seen many times when our big DEs have been beaten one-on-one by athletic QBs in the backfield after a pause, and nobody was around to help...and everyone starts ripping on the DE for doing what Meredith just did; all they can do.
