Look Dak does a lot of things well but he has major limitations.
Has no elite traits.
He'll check down to rbs and TEs before targeting open receivers down field.
Can be wildly inconsistent throwing the ball.
Does not hit receivers in stride or out of breaks.
He's late a lot. He'll either wait too late he has to check down, to late and make the play sacrificing yac, or so late he can't even throw it. Holds the ball at times way too long.
Has trouble diagnosing defensive coverage at times. A lot of times.
Has not shown the ability to make tight window throws or have adequate ball placement on contested catches.
Does not make players around him better.
Mentally has trouble beating better quality opponents.
