Then, he hired a QB - orientated HC to knock the Tedford out of Rodgers.
Rodgers has implied that he ridded himself of the Tedford mechanics, saying that getting back to his conventional high school and junior college mechanics was easy.
The following link shows some high school and JC clips of Rodgers where you see a very recognizable player. Check out the throws starting at the 5:25:

Flash forward to Rodgers rookie preseason. I believe the following clips are in chronological order, with SD being the first preseason game and TEN the last:

Right off the bat, you say "who the hell is that?" relative to the earlier clips. He's got that Tedford ball position up at his ear which everybody talks about. More than that, check out the choppy footwork, both in his drop and when extending plays. This is Teford's idea of how you construct a QB who can get the ball out quick, while the whole affair looks "all arm" and entirely unnatural.
I'm sure the league scouts saw those HS and JC mechanics, but working the pre-draft process they reckoned turning back the clock was not going to be like flipping a switch. After an offseason, OTAs and camp leading up to the first preseason game that switch was not flipped.
By the time you get to the TEN clips you start to see the ball position coming down on some throws and moments of smoother footwork, but he's still not quite there.
Obviously credit goes to Thompson in assessing that the Tedford training could be eventually undone.
Clearly, getting back to his old mechanics was not as easy as Rodgers has portrayed. On the other hand, how much McCarthy had to do with it is debateable. This was not a case of taking a strong-armed athlete and getting him to mechanics he's never had. This was a psychological problem, breaking bad habits that had nonetheless led to prior success. Whatever McCarthy might have contributed to this process would have been in the way of "horse whisperer". I think you have to ask yourself if McCarthy strikes you as that kind of psychological guru, Rodgers' Yoda as it were. That's questionable.
