No, not at all, if anything he's gotten better at sliding around, buying time, but last night nobody was getting open, the Dolphins were aggressive with coverage and only one flag got tossed. Can't blame 'em, if the Ref's are not going to call PI you keep pushing the contact until they do. Missing Gronk hurt's in many ways, he's a great blocker but also draws a crowd when he turn upfield into a route, this give others better chances to get open easier.
I disagree with that. He is the best ever at evading edge rushers. But the interior push still bothers him a lot. Not to say that the things you mentioned aren't significant factors, but I think if we go back and look at Brady's career his biggest weakness was and still is a team that can get strong interior pressure every down.
