I think you are going complete revisionist here.
Martinez:
Fr - 59.2% completions, 8.3 ypa, 10 TDs, 7 INTs, 138.8 rating
So - 56.3%, 7.3 ypa, 13 TDs, 8 INTs, 126.5 rating
Jr - 62.0%, 7.8 ypa, 23 TDs, 12 INTs, 141.6 rating
Sr - 62.7%, 6.1 ypa, 10 TDs, 2 INTs, 140.0 rating
Armstrong:
Fr - 51.9%, 7.37 ypa, 9 TDs, 8 INTs, 124.3 rating
So - 53.3%, 7.81 ypa, 22 TDs, 12 INTs, 133.0 rating
Jr - 55.2%, 7.54 ypa, 22 TDs, 16 INTs, 128.6 rating
I don't know what "general sense" you are talking about. Martinez's worst completion percentage is better that TA's best. Only TA's freshman year - where he played 2/3 of a season - is better that Martinez's worst year throwing INTs. TA only has one year better than any of Martinez's for QB rating.
Now, if you don't like how Martinez looked throwing the ball, that's fine. But he was FAR more effective at doing it that TA. And I'll take production over style points every day of the week and twice on Saturday.
And it's not "nitpicking" to talk about TA's footwork. Martinez's wasn't any good either but he overcame it much better than TA has. For both of them, it's not some footnote. It's the fundamental reason why neither were as good as they could have been.
