As mentioned, he is 5-0 against the Danny Dimes, Taylor Heinickes, Jaylon Hurts. Dak has always been the guy that has to hit the guy open in the zone or busted play deep. He used to have above avg legs. He is not an anticipatory qb, not accurate, and holds the ball too long.
He is a 10-15mm per year middling qb. Manning won a SB bis last year when he was worse than Dak, but that defense was top 4 all time. You can't spend all the money on a middling qb, a crap RB and underused WR and have multiple games where you can't crack 10 points by the 4th qtr
