This is good news. If he knows what he needs to fix, I think he can do it. Tiger Woods changed golf swings several ties in h is career and the golf swing is much more complicated than the football throwing motion. You can see the difference in Dak's 1st 10 games of the season to that spell late in the season where his accuracy fell off a cliff. You can see clearly when he is not in position to throw. and you can see the resulting inaccuracy. The question is why does this breakdown sometimes? He needs to work on that, and if its mental, that may be harder to overcome than the physical breakdowns.
