B.S.
Okay, let's apply the test of logic.
Teams are better prepared against quarterbacks in their second season because they have had a whole year of video/tape to study him with.
Therefore, quarterbacks generally perform more poorly in their 2nd season than in their rookie season.
Uh....no!
Most likely they are employing their own style of logic:
Okay, most quarterbacks would improve in their 2nd year but Dak will be an exception because......well, because nobody can be that good. We analysts couldn't have possibly misevaluated the quarterback with the best rookie performance in history so last season had to be a fluke. This season with right the ship, the world will be normal again once we all see Dak fliounder.
Think again.
.
Who would be the most familiar with Dak'a "weakneases"? That would be his own coaches. In fact, last year they compensated for his main weakness, inexperience.
Last aeason they started vanilla on offense and slowly fed Dak more and more. This season we will all see things we didn't see before from Dak.
How can anyone have the "book" on Dak when only one chapter has been written?
