OK, so we both read the stories - I didn't say he made some kind of historic leap......others might disagree (e.g., going from approx 58% to 71% completion %). I don't think you are appreciating the vast improvements to his mechanics (....Romo's advice was solid) and the touch he is putting on the ball along with dropping it in tight windows vs. throwing 110mph fastballs.
I disagree this is "normal" progress but do agree with your other points about continuity, having a better team around him, etc.
