That's wonderful. What was his record again?
4-8 against teams not named the Giants and Commanders?
If the W/L record matters, Dak is a top 10 QB. Of all the active QB's with at least 1 year, Dak's winning percentage is top 10 in the league. His W/L percentage is better than Wentz, Goff, Foles, Mayfield, Brees and many others. If you are going to use the W/L record as a QB stat, then Dak Prescott already has an incredible body of work. If you're going to pull out the teams in our division that are sub-par, then you need to do the same for every other QB you're judging by the W/L record. Quick fact, the teams with winning records beat most of the teams they play.
Keep in mind, the OP shared REALLY cherry picked stats and I genuinely don't like Prescott holding out for every penny. It's a mistake on his part...and our part. But Prescott is absolutely one of the better QB's in the league and still improving. Last year saw the biggest improvement in his passing skills, IMO.
I don't know what his ceiling is, but I'm enjoying the ride. I think he's foolish for asking for top dollar even if he was the best in the league, which he isn't. The salary cap is going to explode in the next couple of years and his percenteage will quickly level off. BUT, it's still a mistake.
All of that said, you countered the OP's obviously cherry picked stat with your own obviously cherry picked stat.
