Call me what you want, but he isn't a franchise QB1. He makes poor decisions, and hasn't improved over time. Those guys listed above were in rebuild years until they had a solid team. Last year Dak had one.
Stats against the East are weak. Cooper is pretty much exposing Dak for what he really is, an average QB at best. He would not have those numbers if he were in the AFC. He's run them up against weak teams, but not against winning teams. That's what really matters, post season.
Straight from Fan Dual below, which pretty much defines Dak,
"Last season, the Cowboys went 8-8 while Prescott threw 30 touchdowns to 11 interceptions.
However, 22 of those TDs, and just 3 of those INTs, came against teams that missed the postseason. Prescott led the team to a 7-2 record in such contests. However, when facing teams that made the playoffs, the Cowboys went a miserable 1-6, and Prescott tossed 8 scores and 8 picks."
Sorry, but that is the facts, and sums him up perfectly. He's only viewed as top ten, because the NFL is lacking in quality QBs. The FO has a long history of over paying the wrong guys. They screwed the pooch on this one.
Go back and look at what I stated over time. Spend the money on a defense, that win super bowls, even with average QBs sometimes. No great QB won with a mediocre defense. Jerry loves his offense, but last night, that defense won that game.
Cooper isn't fancy, but playing solid football and making good decisions, and also doesn't throw behind his receivers, or into, double and triple coverage. Dak thinks he's better than he really his, where Cooper plays to his ability and strengths.
