Ever since Mankins returned, we've played with a mean edge. But the line was already playing at a good level before that. Opponents and analysts keep saying that Brady is only great because of his O-line. It's obvious that the O-line has to execute but how much is it really about Brady's assignments? So what percentage do you think falls on the O-line executing and what percentage on Brady's calls? Fans keep saying that if Cutler or Sanchez had our O-line, they'd also be elite. I don't really agree.
