Dak's footwork has been a problem and if you watch any tape review by Kurt Warner, Chase Daniels, JT Sullivan, etc...they all comment on Dak's "unconventional" and erratic footwork. Before you wet yourself, not all great QBs have had conventional footwork and even some SB winning QBs like Eli Manning were routinely criticized for throwing off his backfoot.
Dak's footwork has never been good or classic and it's why he has had - so far - streaky accuracy. It's no accident that with more disciplined footwork he's seeing more consistent accuracy.
I didn't say his footwork was good. I said it has improved. it used to be horrible a few years back, and was one of the reasons he took so many sacks, because he would hold the ball until WRs were open, wouldn't throw with anticipation, mostly because he wasn't accurate with the ball and mostly because of his bad footwork.
Kitna helped him a lot, it started to change his game a bit and he has improved since.
do your point, no one is perfect (except I think Aikman came close, he was a classic drop back passer, and its what helped him be so accurate)
